This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.
in_clear <imt>... where each argument to in_clear is an imt identifier. If
any identifiers are incorrect, the incorrect ones will be displayed and no
tables will be cleared. All or nothing.
This fixes the flickering status bar for those renderers that use
scr_copyeverything correctly. sw and sw32. glsl flukes out by not touching
scr_copyeverything and gl is wrong by always clearing it to 0 and never
setting it later.
It seems that SDL_SetColors causes a page flip, so VID_SetPalette only
queue a palette change (by checking for the need to change and storing the
requested palete) and VID_Update now checks for a queued palette change and
updates SDL's palette if required. This fixes the flickering console in sw
-sdl introduced by the cshift/centerprint change.
It turns out the apiprefix define is quite new (I didn't realize it at the
time) and I'd rather get FTBFS reports based on configure catching the
error than gcc catching it.
It seems -ffast-math is not necessarily faster, and the errors it causes
may not be worth the gains, but I'm not sure I want to nuke it completely,
so instead disabling the worst offender of it
(-fno-unsafe-math-optimizations) seems to be the best option. qfbsp now
produces identical text output between optimized and unoptimized builds,
and may be slightly faster than before the change (1.9s for start.map vs
2.0s)
The cshift is now drawn before centerprint, console and the loading plaque.
Unfortunately, due to something odd going on, the sbar stuff is drawn by
the console rather than by Sbar_Draw :P.
Need to up the precision by one due to the difference between g and e, but
much prettier. Might need to rename that function :P I wish I'd thought to
check if g would work, but thanks to divVerent for the suggestion.
It seems the code expected octal escapes to always start with 0. This is
not the case. Also, octal escapes are limited to 3 digits (and hex to 2).
This fixes the garbled bold text in ITS.
It was properly cleared after drawing water chains and sky chains, but I
had missed normal surfaces. It took the use of the same texture for both
normal surfaces and water surfaces to trigger the bug. Thanks go to Simon
'Sock' O'Callaghan and his In The Shadows mod.
This fixes the infinite loop in Sock's shadows mode. Thanks to Spike for
helping me with what should be happening. However, we're still uncertain
about just how the thinktime/sv.time logic should behave.
