49b8ba1f43 Multiple fixes
- Only use dark crimson background in death cam
- vr_directionMode - 0 = HMD, 1 = off-hand
- use a faked positional tracking approach for multiplayer.. in game player location won't change tho, as it is only view translation
- Use the interpolated position for the weapon in a remote server situation, mades weapon movement MUCH smoother

d404519cce Fix rendering IQM models between model frames
For lerped frames (refEntity_t frame not equal oldframe) IQM joint
matrices may have incorrect axis scale. This can cause significant model
distortion. The matrix lerp is linear causing each vector to move in a
straight line between frames instead of arcing like a circle. Each joint
frame can have a different scale so can't just normalize the joint
matrix.

Store joints as quaternions and spherical lerp between them and then
convert to a matrix. For my test model, setting up the skeleton is four
times slower now but it still seems to be fast enough to be usable.

11337c9fa2 OpenGL2: Add GPU vertex skinning for IQM models
Using GPU vertex skinning is significantly faster than CPU vertex
skinning. Especially since OpenGL2 has to run R_VaoPackNormal() and
R_VaoPackTangent() each vertex each frame which causes CPU vertex
skinning to be significantly slower than OpenGL1 renderer.

cccd283be8 Improve IQM CPU vertex skinning performance
Only calculate vertex blend matrix for each unique bone indexes/weights
combination once per-surface instead of recalculating for each vertex.
For best performance the model surfaces needs to use few vertex bone
indexes and weights combinations.

Unroll loops so GCC better optimizes them.

In my tests drawing animated IQM may take 50% as long in opengl1 and
70% as long in opengl2. It will vary by model though and might not
help much at all.

Made unanimated IQM models skip matrix math altogether.

fdc08e860e Improve IQM loading
- Only allocate memory for vertex arrays that are present in the IQM
file and are actually used (may not have colors or blend index/weights,
don't load tangents in opengl1). (Colors is fixed to next commit.)
- Explicitly handle loading IQM files without meshes (bones only).
- Better IQM validation. Header data offset 0 mean data is not present
in file. Check if required vertex arrays are present.

This involved a lot of white space changes and moving code around.

14cc4cc6cb OpenGL2: Fix world VAO cache drawing when glIndex_t is unsigned short
OpenGL ES is only required to support unsigned short for element buffer
values.

R_DrawElements() firstIndex argument was glIndex_t which caused element
indexes to wrap around to 0 when glIndex_t is an unsigned short.
(glIndex_t is an index into the vertexes buffer, not element buffer.)
Change it to 'int' like tess.firstIndex which is passed to
R_DrawElements().

World VAO cache buffer size allowed storing more vertexes than unsigned
short glIndex_t could reference. This resulted in the vertex indexes in
the element buffer wrapping around to 0.

7391215bd4 Don't load non-core GL functions for OpenGL 3.2 core context
Also declare the GL functions in tr_local.h so there is compile error
for non-core GL functions instead of SEGFAULT from dereferencing a NULL
pointer.

Disable the non-functional stencil shadow code that hasn't been updated
to use OpenGL 3.2 core compatible drawing.

Patch for https://bugzilla.icculus.org/show_bug.cgi?id=5931 by

I merged the changes into the OpenGL2 renderer though the fix for
tcMod turb doesn't translate.

904bbc1a8f Allow more than 32 surfaces in skin files
Models don't have a surface limit; skins shouldn't either. Some player
models require more than 32 surfaces since vanilla Quake 3 did not
enforce the limit.

Skins are now limited to 256 surfaces because having no limit would
require parsing the skin file twice. The skin surfaces are dynamically
allocated so it doesn't increase memory usage when less surfaces
are used.
