R_Clear only clears the warpimage part of the screen, leading to an unplayable
HOM effect on the rest of the screen.
The workaround is calling GL_SetCanvas(CANVAS_DEFAULT); at the end of
R_UpdateWarpTextures, it should be harmless enough on other systems, so not sure
if it's worth making this workaround conditional.
My guess is glClear in this implementation is wrongly using glViewport as the
area to clear.

It may be a useful alternative to the existing gamma control for laptops in a bright environment, etc.
(raising contrast gives less of a gray/washed out look than raising gamma, but as a disadvantage, colours near white get clipped to white.)
It's also implemented for both GLSL and SDL gamma ramps, but only if USE_GAMMA_RAMPS is set to 1.
Since USE_GAMMA_RAMPS is 0, currently it only works with GLSL.

"The buffers should always be cleared. On much older hardware, there was a technique to get away without clearing the scene, but on even semi-recent hardware, this will actually make things slower. So always do the clear."
Plus it's nice for map development / debugging.

Previously we were Hunk_Alloc'ing space for 8192 edicts (by default) which zeros all of that memory, this way we only use as much RAM as needed since the unuesd pages aren't dirtied

-adjust release builds to not require 10.6 SDK, and disable PPC since recent OSX SDK's don't support it
-don't strip symbols, to make testing in Instruments easier.

Taken from RMQEngine. the idea is to ensure every -condebug log has the gfx driver version logged.

Some measurements on the size of the sv.edicts hunk allocation, with this change, on various mods (it depends on the number of QC entity fields):
id1 7MB, quoth 11 MB, arcadim 21 MB, rrp 9MB, ne_ruins 16MB.
Since this is a Hunk_Alloc, the whole 10-20MB is cleared to zero which will allocate that much physical ram.
We could probably change it to a malloc later, and not clear the memory, so physical ram is only allocated when the memory is cleared in ED_Alloc.

N.B.: I verified with the OS X Instruments tool that unused space in the heap isn't dirtied (e.g. we never memset the entire heap, only the portions returned by Hunk_Alloc) so this should have no impact on RAM required.

after vid_restart TexMgr_ReloadImage reloads textures to tx->source_width/source_height, which might not match oldsize.
fixes: https://sourceforge.net/p/quakespasm/bugs/13/
steps to reproduce (fixed) bug:
-launch at 640x480, windowed, and with "r_oldwater 0"
-do "map start"
-change to 1024x768 windowed
-change to 1920x1080 windowed
-this last mode change makes liquid textures turn into random garbage.

(640x480 fullscreen -> windowed would give a large 1280x768 window mostly filled with garbage).
Previously, we were only using the fast path on old systems (no VBO support) anyway.

Uses only 36k extra of hunk memory, less for 32-bit builds, so shouldn't have any negative effects.

Fixes a obscure bug where:
- a bsp with no textures (pink checkerboard displayed)
- gamma != 1
- nothing else on screen (sbar hidden, r_drawviewmodel 0)
would result in the screen turning to noise.

Fixes bug where the fog mode was resetting to the default (GL_EXP) after a mode switch, causing fog to look different. This was only affecting SDL1 for me.

With "r_oldwater 0" and "scr_sbaralpha 0", warp textures wouldn't be rendered and instead you would see a copy of the screen tiled where water surfaces should be.

This only affects the case when the developer cvar is set, we already ignore NaN's here.

Initially I thought that we would never need to draw an alias model that hadn't been precached when R_NewMap runs, but this assumption turned out to be incorrect. This fixes the issue where progs/bolt.mdl wasn't rendering in the Scourge Done Slick demos.

This matches the order used in the SDL2 sample applications included with the library.
Seems to fix an issue on Windows 10 with DPI scaling 150%, launching QS 0.90.1 with "-width 1920 -height 1080 -fullscreen", and you get a horrible black flicker every few frames.

This removes the Cache_Flush() call that was here, which was there to fix the jam3_tronyn / low heapsize bug, and instead adds a different workaround for that issue.
