fix q2 prediction. fix q2 saved games issues. fix q2bsp fullbright/fullwhite lights. fix potential issues from svs.clients no longer being preallocated. fix rtlights not doing q1 bsp texture animations. misc crash fixes. hack to allow a clickable hud when using a touchscreen. gl_max_size no longer affects 2d images. select faithful fps preset option by default. gl_font a,b,c works to select fallback fonts. freetype fonts reused to reduce memory usage when the same font is used multiple times either with different sizes or as fallbacks as part of other fonts. allow static member functions. allow static locals. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4552 fc73d0e0-1445-4013-8a0c-d673dee63da5
