Rework the alias vertex shader and rendering code for lerping.
...
Lerping isn't actually done yet (need to get both poses and blend), but
this still renders correctly with blend forced to 0.0.

Upload the normals with the vertex data.
...
Not all hardware can access a texture sampler from the vertex shader, and I
don't want multiple paths this early in the game. Now, vertex normals are
uploaded as shorts. Should be 14 bytes per vertex (was 10, could have been
8 if I had put the normal index with the vertex rather than st).

Enable vis calculation.

One nice thing about this project: I now KNOW that efrags works the way I
wanted it to: all those torches are now toggleable via r_novis :)

Other than novis, they're functionally identical. Now sw and sw32 have
novis as well.

Implement dynamic lighting.
...
This uses the same calculations as the software renderer. However, as the
lightmap calculations are not done yet, if there is no dlight in the
vicinity, there will be no light. demo1 is pretty cool to watch :)

Scale the light level index correctly before colormap lookup.
...
With this, lighting seems to be working. I'm not certain the normals are
100% correct, but I can see something happening on rotating models.

While the first frame was fine, any subsequent ones were not. I had
forgotten that hdr->poseverts held the edited vertex count rather than
hdr->mdl.numverts.

Enable face culling and depth testing.

I spent way too long trying to figure out why triangle order wasn't making
any difference... :P

Make the face culling a little more sensible.
...
GL Quake was weird, culling front faces. Partly understandable, since
Quake's front order is clockwise and GL's default order is
counter-clockwise. However, since the order can be specified, that should
be done instead. Thus, specify the winding order as clockwise (for quake's
data), set culling for back-face removal, and then mess with the winding
direction in the mirror and fish-eye code.

Correct the alias vertex data types.
...
Vertex locations need to be unsigned byte rather than byte (GL is funy
with that). s and t need to be at least short, and since the normal index
is embedded in the st vector, it needs to be the same type. With this, my
test tetrahedrons seem to be working.

Calling programs shaders was a little confusing when I use shader to refer
to the sub-programs (vertex and fragment shaders). Also, print the program
number as well.

The plan is to do interpolated sprites based on a discussion I had with
LordHavoc about them: blending between the two sprite frames. He didn't
mention it, but it looks like blending between the sprite frames' verts is
necessary too.

Work around a bug in mesa.
...
Since I'm not specifying the api when creating my context, mesa is giving
me GL2. This is fair enough, but in GL2, vertex attribute 0 is the vertex
position. This too, is fair enough. The problem is, mesa is assigning 0 to
my vcolor attribute and thus I can't set it. The work around is simply to
swap the declaration order of vcolor and vertex (this really shouldn't work
eiter, I suspect).
