automatic lightmap texture scaling to retain more performance on large maps. r_clutter preliminary implementation should probably fix up the shader still. CSQC_Parse_Damage implemented. finally implement q2 inventory. fix mixer overflow crash. glsl can now use s_diffuse etc to force inclusion of a diffuse sampler/texture, meaning shaders don't need to include them. fix issue with writeip git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4841 fc73d0e0-1445-4013-8a0c-d673dee63da5
