Implement R_IQMGetLerpedFrames().
...
Like R_AliasGetLerpedFrames, but for IQM. It calcualtes the current frame
number and blend between the previous and current frames.

Search for the "nearest" dlights.
...
Nearness is a function of both distance and intensity: distant bright
lights can take priority over close dim lights.

Add a stride field to iqm_t.
...
Since iqm vertex arrays are variable, and I don't want to calculate the
stride every time I render a model, cached the value used when building the
arrays.

Implement IQM animation loading.
...
Bone poses are converted to dual quaternions + shear + scale for nice
skinning. Will likely be slow for software skinning, but too bad.

Add VectorUnshear().
...
VectorUnshear uses the exact same shear vector to remove shear from a
sheared vector. ie with:
VectorShear (shear, v, w);
VectorUnshear (shear, w, x);
x == v within fp math limits.

Add VectorShear and really test Mat4Decompose.
...
And the tests really exercised VectorShear (first attempt had things
messed up when more than one shear value was non-zero). Also,
Mat4Decompose wasn't orthogonalizing the z axis row. Oops. Anyway,
Mat4Decompose is now known to work well, and the usage of its output is
understood :)

Add a function to decompose a matrix.

The function gives rotation(quaternion), scale, shear, and translation (all
three as vectors), shear is (XY, XZ, YZ).

Correct the definition of DualQuatNorm.
...
I'd gotten the norm and magnitude mixed up (partly because the document I
was following got the names mixed up), and then munged the formulas
together.

Make simple gravity acceleration framerate independent.
...
Now it doesn't matter if you get 22 fps or 72, you jump the same height,
which actually happens to be slightly higher than the previous 72fps jump.
Effectively, you jump the height you would if you got infinite fps ;)

Add support for half floats.

iqm and OpenGL use them, so they might come in handy. The tests use values
from wikipedia and a couple extra.

Add a shortcut function for quaterion/vector multiplication.
...
I got the idea from blender when I discovered by accident that quat * vect
produces the same result as quat * qvect * quat* and looked up the code to
check what was going on. While matrix/vector multiplication still beats the
pants off quaternion/vector multiplication, QuatMultVec is a slight
optimization over quat * qvect * quat* (17+,24* vs 24+,32*, plus no need to
to generate quat*).

Do not try to lerp entities when their model changes.
...
This avoids sending invalid pose data to the renderer. The symptom was a
vertex array offset higher than the vertex array size. Discovered by calim
of nouveau while he was debugging a driver problem found by QF. Many
thanks.

Allow alias textures up to 1024x1024.

Blender's default texture size is 1024x1024, and there doesn't seem to be
any reason not to support it.

Ensure code paths stay within the one renderer.
...
The gl renderer calling sw functions is bad news. Still all black, but I
think that's because palette setting is disabled.

Split up the vid plugin init sequence.

This gets gl so it no longer segs. However, the screen remains black
(expect for cshifts).

Separate render module loading from initialization.
...
This allows the vid module to load the render module and access render
specific functions before the renderer initializes, which happens to need
an initialized vid module...

Connect up viddef properly.

Or mostly so, anyway. sw32 is actually putting stuff on the screen.

Start putting the pieces back together.
...
The renderer now gets initialized and things sort of work (qw-client will
idle, though nothing is displayed). However, as the viddef stuff is broken,
it segs on trying to run the overkill demo.
