Need to check for Y inversion separately for src/dest buffers.
If both the src and dest regions are upside down, make them right-side
up for a better chance at a fast path.
progs/tests/copypixrate -blit is much faster now.

A comment alluded to this. Now it's checked.

For the surface_copy() path require same format, no flipping and no stretching.
Fixes progs/tests/copypixrate -blit

The comment disagreed with the code, and nicely drew my eyes to what was
going wrong.

This fixes jerkiness in doom3 and other apps since the kernel change to
throttle less absurdly, which led to a thundering herd of frames.
Because this is a rather minimal fix, there is at least one downside: If
the whole scene completes in one batchbuffer, we'll end up stalling the GPU.
Thanks to Michel Dänzer for suggesting using glFlush to signal frame end
instead of going to all the effort of adding a new DRI2 extension.

Funny thing is I annotated this dependency in
e5f63c403b767f9974e8eb5d412c012b8a69287f, but didn't actually use it.

Compiling mesa on a system with no X headers installed in the default
include paths fails due to missing X11 includes. The header includes are
picked up by configure but not applied.

Windows opengl32.dll calls glFinish prior to every swapbuffers, which
makes it pretty hard to get decent performance...
Work around by mapping finish to flush on PIPE_OS_WINDOWS. This is
conformant, though it might confuse poorly-written benchmarks which
attempt to measure a single event rather than figuring out the rate of
continuous processing.

Some apps enable scissor but set the rectangle to the dimensions of
the window. Don't let this force us onto a slower clear path.

The leading underscore is meaningful... This function is used by
_warning and _error functions as well as the more common
debug_printf().
debug_printf (without underscore) gets turned off when DEBUG is
disabled, but warning/error messages still use this function to get
their message out.

We would have to build the program with the appropriate fog mode, and
also supply the fog coordinate if appropriate.

Otherwise simple apps like glxgears pick up a DirectColor visual since the X
server mixes the depth 32 visual in with the other GLX visuals, and this seems
to result in a (mostly) black screen due to a bad ColorMap for a lot of people.
The bad ColorMap may be a bug in the apps, the X server or X driver, and
regardless of that I think the X server should ideally make the depth 32 GLX
visual separate from the rest again, but in the meantime this makes us cope.
(depth_bits is either 16 or 24, never 0)

I started looking into why _NEW_ARRAY punishes us, and while annotating
dependencies noticed that a bunch of dependencies were missing.

More common. True fix would be to use whatever the screen supports though.

Move a chunk of code out of _mesa_error()

Remove early and unused snprintf and where[] string.
