This fixes the textures (and presumably mesh data) being deleted while
still in use. Oddly, the wait was needed in both brush and alias models
(I expected brush to always come first).
I'm not sure that the mismatch between refdef_t and the assembly defines
was a problem (many fields unused), but the main problem was due to
execute permission on the pages: one chunk of asm was in the data
section, and the patched code was not marked as being executable (due to
such a thing not existing when quake was written).
This is a bit of a hack for now (need to look into maybe using cmem),
but it gets 32-bit windows working for all but the software renderer
(probably just refdef (and maybe viddef) getting out of sync with the
assembly code.
This ensures that fov_y is not calculated until after the render view
size is known and thus doesn't become some crazy angle (that happens to
result in a negative tan). Fixes upside-down-quake :)
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
Not only does it makes sense to centralize the setting of viewport and
scissor, but it's actually necessary in order to fix the upside-down
rendering on windows.
This gets the GL and GLSL renderers working for the -win targets... sort
of: they are upside down and GLSL's bsp surfaces are black (same as
Vulkan). However, with this, all 5 renderers at least limp along for
-win, 4/5 work for -sdl.
It turns out the dd and dib "driver" code is very specific to the
software renderer. This does not fix the segfault on changing video
mode, but I do know where the problem lies: the window is being
destroyed and recreated without recreating the buffers. I suspect a
clean solution to this will allow for window resizing in X as well.
Only 64-bit windows is tested, and there are still various failures, but
QF is limping along in windows again.
nq-sdl works for sw, and sw32, gl and glsl are mostly black (but not
entirely for gl?), vulkan is not supported with sdl.
nq-win works for sw and sw32, and sort of for vulkan (very dark and
upside-down?). gl and glsl complain about vid mode,
qw-client-[sdl,win] seem to be the same, but something is wrong with the
console (reading keyboard input).
The merge with the improvements I made while hacking on csqc (still
undecided as to whether to continue that project) resulted in the size
of the progs string area getting mangled when no heap was allocated for
the progs due to a null zone pointer being used in some pointer
arithmetic. Fixes random(!!!) invalid string error in qfprogs.
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).
It looks like choosing a visual is not necessary (at least for normal
apps, VR might be another matter). Still no idea if anything works (for
-win support in general, let alone vulkan).
This fixes the mightsee updates never occurring, but it doesn't make a
huge difference (though I suppose it might have back in the 90s, or with
a different map).
The stats were being updated before UpdateMightsee was getting called,
and it was incrementing the wrong value (so it would not have been
thread-safe).
While whether it's any faster is debatable (it's slightly slower, but
many more portals are being tested due to different rounding in the base
vis stage), it's certainly easier to read.
