This fixes the segfault and pushes things very much in the desired
direction of proper system independence for rendering and presentation
separation (though things were headed in the right direction before).
This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.
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.
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...
Still, nothing will work: no plugins are loaded and they're all broken
anyway.
glx, sgl, glslx etc are going away, just the basics will be built: fbdev
(probably go away eventually), sdl, x11 and hopefully someday win. That's
actually the only reason anything links.
This has several benifits:
o The silly issue with alias model pitches being backwards is kept out
of the renderer (it's a quakec thing: entites do their pitch
backwards, but originally, only alias models were rotated. Hipnotic
did brush entity rotations in the correct direction).
o Angle to frame vector conversions are done only when the entity's
angles vector changes, rather than every frame. This avoids a lot of
unnecessary trig function calls.
o Once transformed, an entity's frame vectors are always available.
However, the vectors are left handed rather than right handed (ie,
forward/left/up instead of forward/right/up): just a matter of
watching the sign. This avoids even more trig calls (flag models in
qw).
o This paves the way for merging brush entity surface rendering with the
world model surface rendering (the actual goal of this patch).
o This also paves the way for using quaternions to represent entity
orientation, as that would be a protocol change.
for) and "fix" the wayward dlights in mvds: caused by svc_muzzleflash being
written before the player updates. Should probably fix properly that in the
server too.
out into r_graph.c (Time and Z graph), cl_ngraph.c (Net graph), and
{gl,sw}_graph.c (R_LineGraph). gl_ngraph.c is gone. Unfortunatly, something
is rather wrong with NetGraph in gl (probably R_LineGraph).
