Subject: Fix gl_texturecompression_sprites to check for gl_texturecompression. Rough patch... 
X-Git-Tag: xonotic-v0.6.0~163^2~300
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=0137e106705b25124f9bb314f87454109e9d877b;p=xonotic%2Fdarkplaces.git

Fix gl_texturecompression_sprites to check for gl_texturecompression. Rough patch to make v_glslgamma work with 2d graphics (hud, menupics, video etc.).
