fteqw/engine/gl/gl_model.c
Spoike 1b8e779b9b Last fix for skyrooms. Should now show entities in the skyroom. 
Fix a couple of valgrind issues.
Added reason info for when a download fails.
Downloading models now forgets failed-to-load state, fixing a downloaded-but-still-missing bug.
Use anisotropic filtering in more fps_presets.
Fix significant fps loss when using the modelviewer.
First attempt at automatic LOD (supported for md3s and extended-iqms for now).

A quick note on tenebrae and sprites: In tenebrae, sprites are always lit, unless the light_lev field is set (which makes it fullbright).
While its generally preferable and more consistent to assume lit sprites, this is incompatible with vanilla quake and thus unacceptable to us, but you can set the mod_assumelitsprites cvar if you want it.
So for better compatibility, we have a whitelist of 'well-known' sprites that tenebrae uses in this way, which we do lighting on.
You should still be able to use EF_FULLBRIGHT on these, but light_lev is an imprecise setting and will result in issues. Just be specific about fullbright or additive.
DP on the other hand, supports lit sprites only when the sprite contains a ! in its name. We support that too.
