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.
While the main bulk of the improvement (36s down from 42s for
gmsp3v2.bsp on my i7-6850K) comes from using a high-tide allocator for
the windings (which necessitated using a fixed size), it is ever so
slightly faster than using malloc as the back-end.
QF_PROCESS_NEED_LIST is a better name as for one, building no longer
depends on directories, and the directories were lists anyway, so the
name is more generally applicable.
