Spoike 5aa11ddbb1 makefile: attempt to fix freetype when not using makelibs (should make it slightly easier for people to compile with msys2 without needing to resort to cmake). 
emenu: clean up hexen2's maplist options slightly.
emenu: modelviewer should now be slightly more friendly (click+wasd to move around).
particles: fix up randomised s coords.
csqc: try to fix issue with applycustomskin not refcounting properly.
client: [s_]precache and (new) mod_precache cvars can be set to 2 to precache the resources after load, for faster loading at the expense of some early stutter, without risking later mid-game stuttering.
gltf: add support for morphweights in a cpu-fallback path. don't expect good performance on surfaces with morphtargets for now.
gtlf: add some support for gltf1 files. far from perfect.
shaders: gltf1 semantics handling
shaders: const correctness
iqmtool: fix up mdl skin export.
iqmtool: integrate the engine's gltf2 loader. works with animated models, but unanimated ones suffer from basepose-different-from-bindpose issues.
q3bsp: hopefully fixed bih traces. still disabled for now.
qc: change default value of pr_gc_threaded to 1.
qcext: add the '__deprecated' keyword to various symbols in fteextensions.qc, now that fteqcc supports it.
ssqc: spit out a more readable error for WriteByte(MSG_CSQC,...) outside of SendEntity.
ssqc: add registercommand builtin, for consistency with menuqc and csqc (though only one can register any single command).
sv: report userinfo/serverinfo sizes (some clients still have arbitrary limits, plus its nice to see how abusive things are)
sv: try to optimise sv_cullentities_trace a little.
movechain: relink moved ents.
csqc: add spriteframe builtin, for freecs to use instead of more ugly less reliable hacks.
menuqc: fopen("tls://host:port", FILE_STREAM) should now open a tls stream. tcp:// should also work.

//opengl 3 deprecation
. Application-generated object names - the names of all object types, such as
buffer, query, and texture objects, must be generated using the corresponding
Gen* commands. Trying to bind an object name not returned by a Gen*
command will result in an INVALID OPERATION error. This behavior is
already the case for framebuffer, renderbuffer, and vertex array objects. Object
types which have default objects (objects named zero) , such as vertex
array, framebuffer, and texture objects, may also bind the default object, even
though it is not returned by Gen*.
. OpenGL Shading Language versions 1.10 and 1.20. These versions of the
shading language depend on many API features that have also been deprecated.
. Pixel transfer modes and operations - all pixel transfer modes, including
pixel maps, shift and bias, color table lookup, color matrix, and convolution
commands and state, and all associated state and commands defining
that state.
. Legacy OpenGL 1.0 pixel formats - the values 1, 2, 3, and 4 are no longer
accepted as internal formats by TexImage* or any other command taking
an internal format argument. The initial internal format of a texel array is
RGBA instead of 1.
. Texture borders - the border value to TexImage* must always be zero, or
an INVALID VALUE error is generated (section 3.8.1); all language in section
3.8 referring to nonzero border widths during texture image specification
and texture sampling; and all associated state.
