vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.
This cleans up texture_t and possibly even improves locality of
reference when running through texture chains (not profiled, and not
actually the goal).
The static variable meant that Fog_GetColor was not thread-safe (though
multiple calls in the one thread look to be ok for now). However, this
change takes it one step closer to being more generally usable.
Patch found in an old stash.
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.
