fteqw/engine/gl/gl_hlmdl.c
Spoike 53a7b3d47c added support for external capture plugins - and using avcodec as a plugin.c. 
The ragdoll API is potentially usable now, but still really limited.
Enabled SQL requests by default using sqlite. Note that you'll need the sqlite dll to use this. MySQL should still be usable, but I didn't try. MySQL requires -DUSE_MYSQL to compile it, and a dll and -mysql argument to enable it.
Fixed nacl.
NPFTE plugin now invokes an exe to run the game rather than running the game within the browser.
externvalue builtin now accepts & prefix to return a pointer instead.
Fixed vector autocvars.
uri_get, bufstr_add, bufstr_free, now functional.
QC debugger can now show asm if line numbers are not available.
Added support for QC watchpoints. Use the watchpoint command.
gl_specular now give specular even without rtlights, thankfully not as blatently, but its there.
android will not crash due to supported audio formats, and gles2 can be selected via a cvar (requires full FTEDroidActivity/program restart).

this is hellish.
a hl model blends:
4 controllers (on a player, it seems each one of them twists a separate bone in the chest)
a mouth (not used on players)
its a sequence (to be smooth we need to blend between two frames in the sequence)
up to four source animations (ironically used to pitch up/down)
alternate sequence (walking+firing)
frame2 (quake expectations.)
this is madness, quite frankly.
luckily...
controllers and mouth control the entire thing. they should be interpolated outside, and have no affect on blending here
alternate sequences replace. we can just call this function twice (so long as bone ranges are incremental).
autoanimating sequence is handled inside HL_CalculateBones (sequences are weird and it has to be handled there anyway)
this means we only have sources and alternate frames left to cope with.
FIXME: we don't handle frame2.
