6fe32103ea Do a bit of bound() usage auditing.
While these seem to be mostly harmless, having function calls in the
bounded value can be nasty.

12319cfcdf Revert "Slightly reducde the number of calls to glUniformMatrix4fv."
This reverts commit e170f4ee75.

It turns out I messed up something in the patch. I noticed the problem
while playing digs04.bsp: many sub-model surfaces, particularly those with
animated textures, were not being transformed correctly. As this patch did
not make a large performance difference, it's probably better to just
revert it. I might revisit it later.

ede65fb28c Use the correct source for the backtile width/height.
Yay, no more garbage on the screen :)

5014825b39 Fix the backtile for glsl.
Since the backtile is loaded into a scrap and used as a subtexture, we
can't use GL's texture wrapping, thus do the wrapping ourselves. There are
some minor issues with the wrong part of the scrap being drawn: need to
investigate where the bug is (vrect, make_quad, etc).

37260018a2 Acutally use the vertex colors for alias models.
Thanks to Spirit trying QF on nvidia drivers, the missing attributes were
found. Now he shouldn't get gl errors :)

Discovered while getting the location markers working again.

ef9e8d05c4 Avoid some unnecessary state changes.
Doesn't make much difference but it doesn't hurt.

a8e0bcabf9 Call R_SetFrustum in all renderers.
It turns out glsl, sw and sw32 weren't getting any benefit from R_CullBox
because the frustum wasn't setup :P. Get another 8% out of bigass1
(174->184fps). bigass1 now runs 2x as fast as it did before I started this
optimisation run :)

b25de4d995 Rewrite the 2d code to use a scrap.
This severely reduces the calles to BindTexture, and more importantly,
glUseProgram, EnableVertexAttribArray etc. The biggest changes are:

 o  icons and text are all in the one giant texture
 o  icons and text are mixed in the one queue

This gave ~9% speedup for bigass1 (159->174fps).

e170f4ee75 Slightly reducde the number of calls to glUniformMatrix4fv.
It doesn't make a big difference to bigass1 (yet ?), but it does clean up
apitrace a little.

1a6b56b0a2 Call glTexSubImage2D only once per frame.
Instead of once per surface... ouch. Gives about 20% speed boost on demo1
(154.7->185.7)

4da3be5cd6 Get a minor speed gain in glsl bsp rendering.
About 4% (99.5 to 104.4) from not calling VertexAttrib4fv or BindTexture
when not necessary.

f958afad53 Optionally allocate extra data for iqm blend frames.
Also, correct the blend parameter type (int->float. oops).

8ada7c02a3 Remove the vertex scaling.
It was there only because mrfixit is rather small (8qu?) and it made
finding him easier :). Anyway, any scaling should be done in the engine.

31772afd13 Add in some ambient light for iqm models.
Though the bsp loader doesn't yet support colored lighting, the ambient
light will be colored when it does. With this, I guess iqm model support is
done for glsl until I figure out how I want to do dual quaternion support.

0fd2b01665 Update the shader to work as it should :)
I always thought it whould be "light - point" :P. Also, in normal maps, 127
is 0.

c454b96d2a Translate lights into entity space.
Finally, lights work "properly". Probably the nicest lighting we've ever
had :) (still have to put in ambient, though).

a032aa5adf Get the lights working (as such).
They work nicely now when the normal map and texture are bypassed (don't
know what texture is getting used currently).

Now that I have things working... :)

a938c7fb14 Almost fix the animations.
There's still a problem with his finger tips and feet, but the rest of his
limbs seem to be working well. Much thanks to Spike for encouraging me to
do a dump of the matices that are actually sent to the card.

It turns out that animated joints remain relative right up to the last
moment.

7cda91a879 Temporarily disable dual quaternions.
The animation data isn't getting loaded or used properly (not sure yet).
This helps ensure it's not something I've done wrong with dual quats.

c2e0674d50 Implement R_IQMGetLerpedFrames().
Like R_AliasGetLerpedFrames, but for IQM. It calcualtes the current frame
number and blend between the previous and current frames.

099ef348c6 Advance the vertex attrib index.
Disabling the array right after enabling it was causing things to just not
work :P

d1d4c6142c Get the frame data from the right places.

hey, it's a start :)

866c56c236 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.

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

1fd84477a2 Rename char to dchar in the text vertex shader.
Thanks to Spirit :)

Turns out certain drivers (nvidia?) reserve "char" even though opengl does
not. This should fix his missing console text.

3b07928373 Fix an inconsistent numeric constant.
While checking the shaders to see if there might be anything obvious to
work around the current nouveau shader issues, I found a 1 that should have
been a 1.0. I'm surprised it ever compiled.

e784754a11 Disable the gl_triplebuffer check in glsl.
It doesn't seem to have any useful effect in QF (even before the plugin
project) other than setting the number of frames to update. I'm not sure if
it's a useless variable or one where the user is supposed to match it to
the system configuration. Anyway, with this, the glsl plugin now works.

8401704c4e Connect up palette setting for gl and glsl.
The GL plugin now seems to work. GLSL still segs :(

525dbcc13e 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.

898bfa5e5f Split up the vid plugin init sequence.
This gets gl so it no longer segs. However, the screen remains black
(expect for cshifts).

d62772e9cc 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...
