Cosa è cambiato in EDuke32, build per build

center texel fetches for palette lookups and add various optimizations related to indexed texture changes

workaround for texcache expecting all mipmap levels to be available

fix typo causing bug where persistentStreamBuffer was being reset to the config value when it should be disabled

fix bug where polymost2_drawVBO() wouldn't reset the bound buffer state properly for polymost1

adjust parenthesis to cease compiler warnings

streaming VBO optimizations for polymost_drawpoly()

Avoid generation of mipmaps if filter mode isn't set to use them

texture format optimizations
