This adds (unconditional) support for the GE extension. Anything from now on
that sends events in MPX will have to use the GE extension. No GE, no MPX
events. GE is not actually used yet from anywhere with this commit.
You will need to update x11proto, xextproto, libX11, libXext and xcb to the
matching xge branches. Things will _NOT_ work without the updated protocol
headers and libraries.
- Move some code around to minimize diff noise
- Add mmx ops from pixman that never made it into X
- Merge Jeff Muizelaar's bugfixes to fbCompositeSrc_8888x8x8888mmx and
fbCompositeSrc_x888x8x8888mmx.
Before putting anything on the screen, check if the GC was made for the
ScreenRec we want to render to. If not, toss the GC and create a new one. This
is not the best solution but it does the job for now. Same thing for ARGB
cursors except that it's even uglier.
Also remember the screen the cursor was rendered to and check for the right
screen in the BlockHandler, SourceValidate and a few others. Only remove or
restore the cursor if we are rendering to the same screen, otherwise we get
artefacts that are both funky and really annoying.
Requires moving the spriteTrace into the DeviceIntRec and adjusting a few
functions to take in device argument, most notably XYToWindow().
Cursor rendering on the second screen is busted.
Formerly we sized an array with a compile time constant, then initialized
its size to the same constant, but the Linux PCI init code would increase
that "constant". So if you happened to have more than 128 PCI devices,
you'd happily scribble into whatever variables happened to be in .bss
after that array.
Only really fixed for Linux atm. Other OSes will simply (still) fail to
work on video devices above the 128th PCI device.
Fix up the fast-path compositing operators; those are useful for
sources without alpha, but can't be used for sources with
alpha. Also, replaced fbCompositeSrcSrc_nxn with call to fbBlt as
this function must handle 1, 4, 8, 16, 24, 32 bpp objects. Would
be nice to optimize fbBlt for common cases involving 8, 16, 24 and
32bpp.

* Port fix for bug 7685 from pixman. Patch by Carl Worth
* Add projective version of radial gradient code.
* Make sure that all Pict*Gradient types have PictGradient as prefix,
since code in various places relies on that.
Previously the gradient walker was doing excessive resets, (such
as on every pixel in constant-colored regions or outside the
gradient with CAIRO_EXTEND_NONE). Don't do that.
Carl Worth, from pixman
SourceValidate is used exclusively by the software cursor code to pull the
cursor off of the screen before using the screen as a source operand. This
eliminates the software cursor from the frame buffer while painting the
rotated image though. Disabling this function by temporarily setting the
screen function pointer to NULL causes the cursor image to be captured.
(cherry picked from commit 05e1c45ade)
Setting a mode on an unrotated CRTC was causing all of the rotation updates
to be disabled; the loop looking for active rotation wasn't actually looking
at each crtc, it was looking at the modified crtc many times.
(cherry picked from commit 8b217dee3a)
