The attached patch (against quakeforge git) changes the [con]width,
[con]height, and most importantly the rowbytes members of viddef_t
from unsigned to signed int, like in q2. This allows for a properly
negative vid.rowbytes which may be needed in, e.g. a DIB sections
windows driver if needed. Along with it, I changed a few places
where unsigned int is used along with comparisons against the relevant
vid.* members.
One thing I am not 100% sure is the signedness requirements of
d_zrowbytes and d_zwidth: q2 has them as unsigned but I am not sure
whether that is because they are needed as unsigned or it was just an
oversight of the id developers. They do look like they should be OK
as signed int to me, though: comments?

Note from Bill Currie: I had to do some extra changes as many
signed/unsigned comparisons were somehow missed.
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.
The renderer should now be free of any direct access to client code. Even
3d rendering is now done via a function pointer.
The cshift code is done as a 2d screen function.
Don't bother checking vid_gamma for CVAR_ROM becuase it is impossible to
get to VID_UpdateGamma when it is set except for when the cvar is
initially created, and we /want/ the code to execute in that case.
vid.h:
add initialized to viddef_t
vid_common_gl.c:
actually /use/ gammatable (it tends to help)
vid_*.c:
clean up rendundant decls of gammatable, vid_initialized (now
vid.initialized) and make sure vid.initialized gets set.
gl_view.c:
remove gammatable decls
