This new function walks the composite region and calls a rectangle
compositing function on each compositing rectangle. Previously there
were buggy duplicates of this code in fbcompose.c and
miext/rootles/safealpha/safeAlphaPicture.c.
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.

Use the READ and WRITE macros to wrap memory accesses that could be in video
memory. Add MEMCPY_WRAPPED and MEMSET_WRAPPED macros to wrap memcpy and
memset, respectively.
Create fbPrepareAccess macros to call into the driver to set up the
wfbReadMemory and wfbWriteWemory pointers. Call these from fbGetDrawable and
fbGetStipDrawable.
Add the READ and WRITE macros, which expand to simple memory accesses for fb,
and calls through the function pointers for wfb.
Add fbFinishAccess macro to give the driver an opportunity to clean up. Add
calls to this in the appropriate places.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
Changed the semantics of the Convolution filter a bit. It now doesn't try
to normalize the filter values but leaves this to the client. This
gives more reasonable behaviour in the limit where the filter
parameters sum up to 0.
Add MMX implementation of non-repeating source IN repeating mask, aka
"translucent window".
Add MMX implementation of CopyArea.
Use MMX implementation of CopyArea.
Use the new implementations.
Clean-ups and support for AMD64. Bug 1067. Patch by Nicholas Miell
(nmiell@comcast.net)
Add support for AMD64
Many cleanups using <mmintrin.h> instead of __builin_ia32_*, and intrinsics
instead of inline assembly. Also unconditionally use pshufw on AMD64.
s/USE_GCC34_MMX/USE_MMX/g
Call MMX solid fill routine when available.
Call MMX operations when available.
New HasGcc34 macro
New file with many operations implemented with MMX intrinsics, conditional
on having GCC 3.4 on i386.
- fbCombineSaturate was pointed at fbCombineDisjointOver, instead of
fbCombineDisjointOverReverse as it should. Instead, point
fbCombineDisjointOverReverse at fbCombineSaturate (which is likely to
be faster).
- fix previously-unused fbCombineSaturate implementation.
- fbCombineMaskAlphaC was just a copy of fbCombineMaskValueC. Make it do
what it's supposed to (return a cs.alpha).
- fbCombineAtopC didn't invert the source alpha value.
- fix copy'n'paste errors in fbCombine(Dis/Con)jointGeneralC, also source
alpha wasn't treated in a component fashion.
- fbCompositeSrc_8888* didn't handle when the source lacks an alpha
channel. Rather than adding that and possilby slowing down the (normal)
alpha case, don't let x8r8g8b8/x8b8g8r8 Pictures be used in
fbCompositeSrc_8888* because Over with one of these is just Src.
