Subject: Don't Mod_BuildTextureVectorsFromNormals if 2D. 5-10% performance improvement
X-Git-Url: https://de.git.xonotic.org/?p=xonotic%2Fdarkplaces.git;a=commitdiff_plain;h=055003a1c78341222d3909cea3413de18808a621;hp=8c1799cb28a10745836509e202ef6e85df5d5e70

Don't Mod_BuildTextureVectorsFromNormals if 2D. 5-10% performance improvement

This is likely not needed for 2D and there doesn't appear to be any
defects, visual or otherwise.
