Added Z_EXT_PF_ONGROUND + Z_EXT_PF_SOLID for compat (not enabled serverside due to conflicts with pext - just a define away). Fixed bug with loading screens switching sizes part way through loading. Added hexen2 rain effect. Fix hexen2 model texture alphas not working. Fix potential linux crash from excessively long stdin lines. Added cl_rollalpha cvar. Fixed quirk where the player would slide along the base of steep walls/slopes. Tweaked PM_NudgePosition to be more precise, giving more reliable prediction. Fixed fread qc builtin. Tweaked random() builtin to bias slightly away from 0, so that nextthink=random()*foo; will never cause statue-monsters. Check for GL_WEBGL_depth_texture instead of just GL_OES_depth_texture, to fix compressedTex2d errors in firefox. Second attempt at blocking invariant keyword with mesa. Use xrandr for gamma where possible. This prevents reading stale XF86 gamma ramps and restoring those invalid ramps when quitting. Try to grab mouse pointers slightly faster in x11. Don't call XIFreeDeviceInfo if XIQueryDevice returned NULL. Document parm_string and startspot qc globals. Fix possible infinite loop from physics frames. QTV: stripped most of the old plugin code (because really, who has a browser that still supports either ActiveX or NPAPI). Fixed up emscripten port references. QTV: fix bug with protocol extensions not being reported to viewers. QTV: use binary websockets instead of text. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5419 fc73d0e0-1445-4013-8a0c-d673dee63da5
