Before this commit, updates to the bitmap font in the graphics window
cause missing characters in the text window and vice versa. This is
because BitmapFont contains a texture that's mutated, and sharing it
would also require sharing display lists between GL contexts, which
is not done (and overly complicated for this case anyway).
Before this commit, dragging a new rect would result in one
of the lines lagging behind, because it is drawn in the middle
of regeneration. After this commit, the rectangle stays rectangular.
For a reason I do not understand, this only fixes Win32; GTK
continues to exhibit the bug, whereas Cocoa has never exhibited it
but the render latency seems to have lowered slightly.
It's a deprecated platform that has weird OpenGL-related bugs and
is incompatible with using EGL anyway. It was clear we're going
to drop it, the only question was when. Answer: now.
Before this commit, when an entity is clicked at or dragged, and it
shares a place with other entities, which of them is selected is
decided more or less at random. This is particularly annoying when
dragging.
After this commit, when clicking, an entity from the current group
is given preference, and when dragging, an entity from a request
is given preference. This allows e.g. dragging points of a sketch
even when an extrusion of that sketch is active.
Before this commit, it was possible to add some redundant constraints
(e.g. vertical, horizontal or midpoint) without failing the sketch,
because SolveBySubstitution() removed the redundant equations.
However, this could result in the solve failing later because
the system didn't converge, without any pointers as to the true
cause of the failure.
After this commit, any transparent triangles are drawn last, which
causes them to not clobber the depth buffer, and so if they overlap
some opaque triangles, then these opaque triangles will be visible.
There are still issues with overlapping transparent triangles,
and with transparent triangles overlapping outlines and entities.
It was broken because of three bugs:
* Uninitialized variables in RunCommand;
* Trying to use (OEM-encoded) main() argc/argv arguments instead
of GetCommandLineW();
* Trying to pass relative paths directly into ssfopen.
This commit fixes four issues:
* Instead of WRITE,APPEND, resource.rc was generated using
WRITE,WRITE, which erased #include <windows.h> and prevented
any symbolic definitions (like RT_MANIFEST) from working.
This silently included them using a string type instead,
which did nothing.
* WINVER is bumped to Win7, since that's what we target now.
* Index of RT_MANIFEST is changed to 2, since that's what
it has to be when ISOLATION_AWARE_ENABLED is defined.
* Platform is not restricted to X86 in manifest, since there
is no point in doing so.
Before this commit, if constraints with newly introduced params were
loaded from a file that linked other files, the upgrade code would
attempt to look up a non-existent entity.
All of our executables need resources; e.g. the vector font is
a resource and it is necessary for generation. Before this commit,
the GUI executable loaded the resources in a nice way, and everything
else did it in a very ad-hoc, fragile way.
After this commit, all executables are placed in <build>/bin and
follow the same algorithm:
* On Windows, resources are compiled and linked into every
executable.
* On Linux, resources are copied into <build>/res (which is
tried first) and <prefix>/share/solvespace (which is tried
second).
* On macOS, resources are copied into <build>/res (which is
tried first) and <build>/bin/solvespace.app/Contents/Resources
(which is tried second).
In practice this means that we can add as many executables as we want
without duplicating lots of code. In addition, on macOS, we can
place supplementary executables into the bundle, and they can use
resources from the bundle transparently.
Before this commit, inserting into BSP tree could easily overflow
the stack because we allocate very large stack frames and, on
convex geometries (e.g. a sphere), the BSP tree degenerates into
a "BSP list", thus requiring one large stack frame per triangle.
This can be reproduced by exporting a 2d shaded view of sphere.
After this commit, the stack frames only contan a pointer to
a supplementary data structure, and moreover it only allocates
its fields on demand, conserving heap memory as well.
As a side effect, an arbitrary classifier limit of 50 vertices
is removed.
