Rendering and textures are limited to 8kx8k, but mesa limits things to
4kx4k, and magic guard band stuff may break on 8kx8k drawing. This is safe
though, and makes compiz work on bigger screens.

Tries to use either GLX_MESA_swap_control or GLX_SGI_video_sync to
detect whether the display is synchronized to the vertical blank. If
it detects this, a message will be printed. HOPEFULLY this will
prevent some of the bug reports such as "glxgears only gets 59.7fps.
What's wrong with my driver?"
We can support any combination of (a8r8g8b8, x8r8g8b8, r5g6b5) x (z0,z24,z24s8)
on either class of chipsets. The only restriction is no mixing bpp when also
mixing tiling. This shouldn't be occurring currently.
On newer GCC releases, the compiler's headers have been split between
the include and include-fixed directories. Add both if the directories
exist.

Anytime we're not rendering to the default/window FBO, need to invert
rendering, not just when rendering to a texture. Otherwise, if a FBO
consists of a mix of textures and renderbuffers the up/down orientation
was inconsistant.
Fixes shadowtex.c bad rendering.
When glTexImage() is called we need to re-validate any FBOs that point to
the texture (i.e. render-to-texture) since changing the texture's size/format
will effect FBO completeness.
We don't keep a list of all FBOs rendering into each texture (which would be
a bit messy) so we check all FBOs in existance. To optimize this, the
gl_texture_object->_RenderToTexture flag is used to avoid checking textures
that have never been used as renderbuffers. So, we only walk over all FBOs
(there's usually only a few) when glTexImage() modifies a RTT texture.
Fixes a bug seen in shadowtex.c when toggling packed depth/stencil mode.
