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.

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.

5909b9a1cf Isolate the Altivec code so non-Altivec PPC targets can use the same binary.
Moved all the code using Altivec intrinsics to separate files. This 
means we can optionally use GCC's -maltivec on just these files, which
are chosen at runtime if the CPU supports Altivec, and compile the rest
without it, making a single binary that has Altivec optimizations but
can still work on G3.

Unlike SSE and similar extensions on x86, there does not seem to be
a way to enable conditional, targeted use of Altivec based on runtime
detection (which is what ioquake3 wants to do) without also giving the
compiler permission to use Altivec in code generation; so to not crash
on CPUs that do not implement Altivec, we'll have to turn it off
altogether, except in translation units that are only entered when
runtime Altivec detection is successful.

This has been tested on Linux PPC (on an Altivec-enabled CPU),
but we may need further work after testing trickles out to other
PowerPC devices and ancient Mac OS X builds.

I did a little work on this patch, but the majority of the effort belongs 
to Simon McVittie (thanks!).

59b1262b82 Fix floating point precision loss in renderer [part 2]
Fix floatTime using float precision instead of double using GCC.
Fix R_BindAnimatedImage to be in sync with function table.
Fix vertexDeform bulge, vertexDeform normals, noise wave function
at high level time.

Revert unnecessary float -> double conversions.

30fdd88c9f Fix floating point precision loss in renderer [part 1]
Patch for https://bugzilla.icculus.org/show_bug.cgi?id=5931 by
Eugene C. from 2013 plus recent fix for tcMod rotate.

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.

60d28722ef Remove unfinished OpenGL display list code
It seems unlikely anyone is going to do anything with this aside from stub
it out in OpenGLES ports.

0bf1f3d0ba Add support for IQM int blend indices and float blend weights
Integer blend indices are converted to bytes at load, ioq3 doesn't allow more than 128 joints.

Heavily based on code by @zippers.
