The problem was first introduced here:
dabd57847e
and later "fixed" here:
f324477dd0
by setting the stack size to /STACK:33554432
Solvespace now starts up even with /STACK:554432
According to this:
https://en.cppreference.com/w/cpp/language/value_initialization
```
"2) if T is a class type with a default constructor that is neither user-provided nor deleted (that is, it may be a class with an implicitly-defined or defaulted default constructor), the object is zero-initialized and then it is default-initialized if it has a non-trivial default constructor; "
```
So removing the `{}` should leave both the `System` and `TextWindow` class instances properly initialized.
A warning found with /W4 by MSVC 2019 (Microsoft (R) C/C++ Optimizing Compiler Version 19.24.28314)
is an actual bug. How does the SpaceMouse (I do not have one) work at all when the global `hSpaceWareDriverClass` is NULL?!

GetIdent is called from an UI event callback, at which point there
might well not be an active GL context. Before this commit, that
would return a NULL pointer and result in a crash.
Before this commit, certain fonts (e.g. Terminus) would appear in
the selector but cause a crash (assertion failure) if they are used.
After this commit, we make sure all preconditions are met before
showing a font there.
Also, improve error reporting to always print font filename.
This was originally changed in 74aa80b6, but the fix broke stipping
because it incorrectly changed the logic. Revert that, and just make
the textures smaller instead.
Before this commit, resizing the property browser would cut off
the rows at the bottom, or else add black space, until next refresh.
This could be perhaps more elegantly done by adding an onResize event
but given that each of them would be followed by onRender anyway, it
seems there's no benefit to adding onResize.
As I understand it, both glGetError() and glFinish() are serializing
and blockig, so it makes more sense to call them at the same time.
glFlush() does not block.
Since Catalina or earlier this no longer causes artifacts when Cocoa
controls are overlaid on a GL layer. Conversely, offscreen rendering
is very slow, especially on HiDPI screens.

When drawing the graphics window, we flush it twice: once to draw
the geometry, and another time to draw the UI overlay (toolbar,
selection marquee, and FPS counter). Calling glFinish() each time
is (on most platforms) just pointlessly slow, but on macOS Catalina,
without offscreen rendering, it causes the toolbar to flicker.
Instead of calling glFinish() twice per frame in that case, call
glFlush() twice and then glFinish() once we really are done.
Union and difference are optimized by replacing the expression
(!inShell && !inFace)
which is equivqlent to
(!inShell && !inSame && !inOpp)
with
outSide
which is equivalent, since SShell::Class::OUTSIDE is the only remaining possibility.
Per the OpenGL documentation:
> GL_INVALID_VALUE may be generated if level is greater than
> log2(max), where max is the returned value of GL_MAX_TEXTURE_SIZE.
Although we always passed `log2(max) + 1` as `level`, for some reason
none of the GL implementations we run on ever returned an error.
It also appears there is a bug in ANGLE that crashes the process
instead in this case if the C++ runtime performs bound checks on
vector::operator[]=.
Was getting segfaults near here with another patch since removed from the branch.
Moving these assignments after the memfree means they still have
useful data when debugging a crash in memfree.
Allows distancing users from the internal "elem" member.
Add Get() and operator[].
Replace direct references to elem.
Make elem and elemsAllocated private in IdList/List.
In other words, Ctrl inverts the normal action of LMB. It is already
possible to deselect entities through the context menu, but that
can be very awkward on laptop touchpads with a crowded sketch; with
Ctrl, a misclick is easily corrected without moving cursor at all.
This means that automatically added H/V constraints now will never
cause the sketch to become overconstrained, which currently makes
that feature almost unusable.
It makes no sense to solve by substitution (therefore weakening rank
check) in SolveRank(), since that's the whole point of SolveRank().
In addition, because SolveRank() is currently always called right
after AddConstraint(), forceDofCheck would always be true anyway.
In addition, it makes no sense to have TestRankForGroup() dependent
on the result of the previous solve. (For SolveGroup(), solving by
substitution after we know that rank test succeeds makes dragging
points much faster.)
Clarify the name of the command, as the old name is not strictly
correct. E.g. consider a vertical line with a midpoint constraint to
origin has 1 DOF, but 2 highlights are shown. Conversely, a single
datum point has 2 DOF, but 1 highlight is shown.
Supported metric units: km, m, cm, mm, µm, nm.
Supported USCS units: in, mil, µin.
Also, use the newly introduced unit formatting machinery in tools for
measuring perimeter, area and volume, so that e.g. volume is not
displayed in millions of cubic millimeters.
