Changes in preparation for the release of SolveSpace under the GPL, to add that license, and change all copyright notices to me, not Useful Subset, LLC. [git-p4: depot-paths = "//depot/solvespace/": change = 2211]

// Implementation of the Group class, which represents a set of entities and
// constraints that are solved together, in some cases followed by another
// operation, like to extrude surfaces from the entities or to step and
// repeat them parametrically.

Bits and pieces of SolveSpace; zoom works now, and some stuff to draw planes that I will use to do the datum planes. Still haven't settled upon the request/entity/group structure, and that's the dependency before doing much real. [git-p4: depot-paths = "//depot/solvespace/": change = 1656]

#include "solvespace.h"
Add transformed points and normals with a rotation (as well as a translation; or equivalently, rotation about an arbitrary axis). Those will be important for step and repeats, and for imported parts. Also fix a terrible memory corruption bug: I was freeing the remap list after I loaded it from the file, but the code that put that into the SS.group list made only a shallow copy.

Check in some SolveSpace stuff, even though I didn't make much progress. I want to change the sketch.h stuff fairly significantly, I think, before proceeding. [git-p4: depot-paths = "//depot/solvespace/": change = 1657]

const hGroup Group::HGROUP_REFERENCES = { 1 };
Add selectable faces, by associating an hEntity with the triangle's metadata. And add point-on-face constraints to go with that. Still needs some cleanup for the user interface. [git-p4: depot-paths = "//depot/solvespace/": change = 1766]

Fix a gross memory leak: when switching to a new file, either after File -> New or File -> Open, I freed the Group structures themselves, but none of their children. [git-p4: depot-paths = "//depot/solvespace/": change = 2120]

Add the first `derived' group, that generates entities based on other entities. This requires a new point type, for a point that's defined as a transformation of some other point. All works nicely, I think. There's ugliness because entities are no longer guaranteed to have a parent request. Also speed up display of the text window, by caching brushes instead of recreating for each character (!), and add a bit more user interface in the text window.

void Group::AddParam(IdList<Param,hParam> *param, hParam hp, double v) {
Replace all ZERO and memset with C++11 brace-initialization. This will allow us to use non-POD classes inside these objects in future and is otherwise functionally equivalent, as well as more concise. Note that there are some subtleties with handling of brace-initialization. Specifically: On aggregates (e.g. simple C-style structures) using an empty brace-initializer zero-initializes the aggregate, i.e. it makes all members zero. On non-aggregates an empty brace-initializer calls the default constructor. And if the constructor doesn't explicitly initialize the members (which the auto-generated constructor doesn't) then the members will be constructed but otherwise uninitialized. So, what is an aggregate class? To quote the C++ standard (C++03 8.5.1 §1): An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3). In SolveSpace, we only have to handle the case of base classes; Constraint and Entity have those. Thus, they had to gain a default constructor that does nothing but initializes the members to zero.

A monster change to add support for filled paths. This requires us to assemble Beziers into outer and inner loops, and find those loops made up of entities with filled styles. The open paths are maintained in a separate list, and we assemble as many closed paths as possible even when open paths exist. This changes many things. The coplanar check is now performed on the Beziers, not the resulting polygon. The way that the polygon is used to determine loop directions is also modified. Also fix the mouse behavior when dragging a point: drop it when the mouse is released, even if it is released outside the window, but don't drop it if the pointer is dragged out of and then back into our window. Also special-case SSurface::ClosestPointTo() for planes, for speed. [git-p4: depot-paths = "//depot/solvespace/": change = 2058]

Renamed the RGB() macro to RGBi() to avoid collisions with Microsoft Microsoft defines an RGB() macro that at one point was compatible with our version (returning a packed integer containing 8-bit red, green and blue channels), but is no longer, and the incompatibility led to an awkward situation in w32main.cpp where we had to restore Microsoft's form of the macro in order for the commctrl.h header to compile. By renaming the macro to RGBi()---analogous to the RGBf() macro we already define---we avoid the hassle entirely.

g.color = RGBi(100, 100, 100);
A big nasty change, originally just to add paste transformed. So it does that, and adds a scale factor to that transformation (instead of just mirroring, as before), but also: * Replace the "import mirrored" mechanism with a scale factor, which if negative corresponds to a reflection as well. * Fix self-intersection checker to report a meaningful point when edges are collinear. * Don't blow an assertion on some types of invalid file; instead provide a nice error message to the user. * Clear the naked edges before each regen. * Don't create zero-length line segments by snapping a line segment's end to its beginning.

Initial work on the assembly (`import') feature. I can import a part, including all of its entities and the triangle mesh.

Rewrite all path handling with std::string. What do we gain from this? Several things. * First, usage of PATH_MAX (the POSIX constant) is eliminated. PATH_MAX is actually a lie; Linux and OS X (and probably other BSDs too) do not have an actual path length limit. Linux claims 4096, OS X claims 1024, but it is trivial to construct paths that are longer. * Second, while Windows does enforce a limit of MAX_PATH (the Win32 constant) for its ASCII functions, the Unicode variants, when used with UNC paths, do not have this restriction. The capability to use UNC paths is useful by itself, as it allows to access files on network shares directly. * Third, representing paths as std::string will make it easier to interoperate with *W WinAPI functions later.

Find a memory corruption! I was getting a pointer into the entity list, and then adding a new entity to that list, and then looking at that pointer again.

Replace NameStr with std::string. This removes the arbitrary 64 byte restriction (which effectively limits us to as little as 16 Unicode characters with CJK encodings), makes classes smaller, and is easier to use. As a consequence of making the length of all ex-NameStr fields unbounded, all functions that returned a buffer derived from those were changed to return std::string. Then, functions that are contextually similar to the ones described above were changed to return std::string. Then, functions that now happened to mostly take an std::string argument converted to a C string were changed to accept std::string. This has produced a bit of churn, but is probably for the better.

Use C++ std::{min,max,swap} instead of custom ones. The main benefit is that std::swap will ensure that the type of arguments is copy-constructible and move-constructible. It is more concise as well. When min and max are defined as macros, they will conflict with STL header files included by other C++ libraries; in this case STL will #undef any other definition.

Find a memory corruption! I was getting a pointer into the entity list, and then adding a new entity to that list, and then looking at that pointer again. Not okay; the add operation might have forced a realloc. I have to watch for that. And add a "distance ratio" constraint, plus a new kind of group that comes with its own workplane. The workplane is not solved for; it's generated explicitly in terms of elements that are already solved. [git-p4: depot-paths = "//depot/solvespace/": change = 1716]

Rigorously treat paths on every platform. After this commit, SolveSpace deals with paths as follows: * Paths are generally treated as opaque platform-specific strings. This helps on Linux, because paths on Linux don't have any specific encoding and it helps to avoid any operations on them. * The UI in some places wants to get a basename. In this case, the newly introduced PATH_SEP is used. This allows to treat backslash as a regular character, which it is on Linux and OS X. * The only place where any nontrivial operations on paths are performed is the g->impFile/impFileRel logic. Specifically, when saved, g->impFile always contains an absolute path with separators of the current platform, and g->impFileRel always contains a relative path with UNIX separators. This allows to treat backslash as a regular character. Old files will contain g->impFileRel with Windows separators; these are detected by looking for a drive letter in g->impFile and in that case mapping Windows separators to UNIX ones. There is no need to treat UNIX separators (forward slashes) in any special way on Windows because there is no way on Windows, not even via UNC paths, to create or address a directory entry with a forward slash in its name.

Replace NameStr with std::string.

We now have selective solve; a group (and all the groups afterward) becomes dirty when the user makes a change, and only the dirty groups get solved. That's a huge effective speedup. Also add delete function for groups. That has an interesting issue; it actually ends up recursing on GenerateAll(), since GenerateAll() calls ClearSuper(), ClearSuper() might need to recreate a group (if all the groups were deleted), and that would activate the group, which calls GenerateAll.

Replace all ZERO and memset with C++11 brace-initialization. This will allow us to use non-POD classes inside these objects in future and is otherwise functionally equivalent, as well as more concise. Note that there are some subtleties with handling of brace-initialization. Specifically: On aggregates (e.g. simple C-style structures) using an empty brace-initializer zero-initializes the aggregate, i.e. it makes all members zero. On non-aggregates an empty brace-initializer calls the default constructor. And if the constructor doesn't explicitly initialize the members (which the auto-generated constructor doesn't) then the members will be constructed but otherwise uninitialized. So, what is an aggregate class? To quote the C++ standard (C++03 8.5.1 §1): An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3). In SolveSpace, we only have to handle the case of base classes; Constraint and Entity have those. Thus, they had to gain a default constructor that does nothing but initializes the members to zero.

Add a setting that permits a group to include redundant constraints. This setting is generally useful, but it especially shines when assembling, since the "same orientation" and "parallel" constraints remove three and two rotational degrees of freedom, which makes them impossible to use with 3d "point on line" constraint that removes two spatial and two rotational degrees of freedom. The setting is not enabled for all imported groups by default because it exhibits some edge case failures. For example: * draw two line segments sharing a point, * constrain lengths of line segments, * constrain line segments perpendicular, * constrain line segments to a 90° angle. This is a truly degenerate case and so it is not considered very important. However, we can fix this later by using Eigen::SparseQR.

Replace all ZERO and memset with C++11 brace-initialization. This will allow us to use non-POD classes inside these objects in future and is otherwise functionally equivalent, as well as more concise. Note that there are some subtleties with handling of brace-initialization. Specifically: On aggregates (e.g. simple C-style structures) using an empty brace-initializer zero-initializes the aggregate, i.e. it makes all members zero. On non-aggregates an empty brace-initializer calls the default constructor. And if the constructor doesn't explicitly initialize the members (which the auto-generated constructor doesn't) then the members will be constructed but otherwise uninitialized. So, what is an aggregate class? To quote the C++ standard (C++03 8.5.1 §1): An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3). In SolveSpace, we only have to handle the case of base classes; Constraint and Entity have those. Thus, they had to gain a default constructor that does nothing but initializes the members to zero.

Note that there are some subtleties with handling of brace-initialization. Specifically: On aggregates (e.g. simple C-style structures) using an empty brace-initializer zero-initializes the aggregate, i.e. it makes all members zero. On non-aggregates an empty brace-initializer calls the default constructor. And if the constructor doesn't explicitly initialize the members (which the auto-generated constructor doesn't) then the members will be constructed but otherwise uninitialized.

The coplanar check is now performed on the Beziers, not the resulting polygon. The way that the polygon is used to determine loop directions is also modified. Also fix the mouse behavior when dragging a point: drop it when the mouse is released, even if it is released outside the window, but don't drop it if the pointer is dragged out of and then back into our window.

Replace all ZERO and memset with C++11 brace-initialization. This will allow us to use non-POD classes inside these objects in future and is otherwise functionally equivalent, as well as more concise. Note that there are some subtleties with handling of brace-initialization. Specifically: On aggregates (e.g. simple C-style structures) using an empty brace-initializer zero-initializes the aggregate, i.e. it makes all members zero. On non-aggregates an empty brace-initializer calls the default constructor. And if the constructor doesn't explicitly initialize the members (which the auto-generated constructor doesn't) then the members will be constructed but otherwise uninitialized. So, what is an aggregate class? To quote the C++ standard (C++03 8.5.1 §1): An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3). In SolveSpace, we only have to handle the case of base classes; Constraint and Entity have those. Thus, they had to gain a default constructor that does nothing but initializes the members to zero.

Replace NameStr with std::string. This removes the arbitrary 64 byte restriction (which effectively limits us to as little as 16 Unicode characters with CJK encodings), makes classes smaller, and is easier to use. As a consequence of making the length of all ex-NameStr fields unbounded, all functions that returned a buffer derived from those were changed to return std::string. Then, functions that are contextually similar to the ones described above were changed to return std::string. Then, functions that now happened to mostly take an std::string argument converted to a C string were changed to accept std::string. This has produced a bit of churn, but is probably for the better.

So it does that, and adds a scale factor to that transformation (instead of just mirroring, as before), but also: * Replace the "import mirrored" mechanism with a scale factor, which if negative corresponds to a reflection as well. * Fix self-intersection checker to report a meaningful point when edges are collinear. * Don't blow an assertion on some types of invalid file; instead provide a nice error message to the user. * Clear the naked edges before each regen. * Don't create zero-length line segments by snapping a line segment's end to its beginning.

A big change, to add a concept of normals. These are "oriented vectors", represented by unit quaternions. This permits me to add circles, where the normal defines the plane of the circle. Still many things painful. The interface for editing normals is not so intuitive, and it's not yet clear how I would e.g. export a circle entity and recreate it properly, since that entity has a param not associated with a normal or point. And the transformed points/normals do not yet support rotations. That will be necessary soon. [git-p4: depot-paths = "//depot/solvespace/": change = 1705]

Add the first `derived' group, that generates entities based on other entities. This requires a new point type, for a point that's defined as a transformation of some other point.
