        * src/icimage.c:
        (premultiply):
        (INTERPOLATE_PIXEL_256):
        Use uint32_t instead of uint;

2006-01-04  Carl Worth  <cworth@cworth.org>

	* Originally: 2005-10-10  David Reveman  <davidr@novell.com>

	* src/fbcompose.c: (SourcePictureClassify), (fbFetchSolid),
	(fbFetch), (fbFetchSourcePict), (fbFetchTransformed),
	(fbFetchExternalAlpha), (fbCompositeRect):
	* src/icimage.c: (_pixman_init_gradient),
	(_pixman_create_source_image),
	(pixman_image_create_linear_gradient),
	(pixman_image_create_radial_gradient):
	* src/icimage.h:

	Some major performance improvements to the general composite code
	used for gradients and transformed images. Like fetching of mask
	scanline before source scanline so that only the necessary pixels
	from source needs to be computed in case of gradients or
	transformed images as source. This patch also include some
	gradient specific fixes and performance improvement.

2006-01-04  Carl Worth  <cworth@cworth.org>

	* Originally: 2005-10-10  David Reveman  <davidr@novell.com>

	* src/pixman.h: Add entries for gradient support.

	* src/icint.h: Add PictureGradientColor.

	* src/icimage.h:
	* src/icimage.c: Add necessary functionality for gradient support.

	* src/fbcompose.c: Enable gradient support.

2005-11-21  Carl Worth  <cworth@cworth.org>

	* src/pixman-remap.h: Remove duplicate definitions of
	pixman_color_to_pixel and pixman_composite.

2005-11-18  Carl Worth  <cworth@cworth.org>

	* src/pixman-remap.h: Remove spurios INT_ prefixes which break the
	build with very recent binutils.

2005-10-09  Billy Biggs  <vektor@dumbterm.net>

	* src/icimage.h: Make space for the new bits needed by expand.

2005-10-09  Billy Biggs  <vektor@dumbterm.net>

	reviewed by: davidr, cworth, otaylor

	* src/pixman.h: Add extended repeat modes, copied from XRender.
	* src/icimage.c: (pixman_image_init), (pixman_image_set_repeat),
	(FbClipImageSrc): Cleanup to use the new repeat modes.
	* src/icrect.c: (pixman_fill_rectangles): Be explicit about which
	repeat mode we want.

2005-09-18  Billy Biggs  <vektor@dumbterm.net>

	* src/fbmmx.c: Only include xmmintrin.h if USE_SSE is defined.

2005-09-15  Billy Biggs  <vektor@dumbterm.net>

	Bug #4414, reviewed by otaylor, cworth.

	* src/fbmmx.c: Remove CPU detection code.
	* src/fbpict.c (detectCPUFeatures), (fbHaveMMX): Move CPU
	detection code out of the MMX file and into the generic code to
	avoid compiling it with -mmmx and -msse.  Using these options
	causes gcc to use MMX and SSE instructions in the CPU detection
	code which causes SIGILLs on older processors.

2005-08-28  Owen Taylor  <otaylor@redhat.com>

	Bug #4260, Reviewed by B. Biggs
 
 	* src/fbcompose.c (fbStore_a8b8g8r8, fbStore_x8b8g8r8): Use & not
 	&& for bitwise AND.
 
 	* src/fbpict.h (fbComposeGetSolid) src/fbpict.c src/fbmmx.c: Take
 	'dest' as an argument, if pict and dest don't match for RGB, BGR,
 	swap result.
	
2005-08-28  Owen Taylor  <otaylor@redhat.com>

	* src/fbmmx.c (detectCPUFeatures): Use local labels rather than
	global labels in the assembly, to be robust if the code is inlined
	in multiple places. (#4283, Reported by Marco Manfredini)

	(fetchPixelProcForPicture), (storeProcForPicture), (fbFetchSolid),
	(fbFetch), (fbFetchTransformed), (fbStore), (fbStoreExternalAlpha),
	(fbCompositeRect):

	* src/fbmmx.c (detectCPUFeatures): Make the code work with
	-fomit-frame-pointer by making sure that %esp isn't modified at
	the point where we access output operands. (#4269, Patch from
	Ronald Wahl)
	
2005-08-22  Owen Taylor  <otaylor@redhat.com>

	* src/pixregion.c (pixman_region_union_rect): When width/height
	are 0, copy the src to the dest, don't just return. (#3017)

2005-08-21  Billy Biggs  <vektor@dumbterm.net>

	* src/pixman-remap.h: Fix a typo in the last change.

2005-08-21  Billy Biggs  <vektor@dumbterm.net>

	* src/fbpict.c: Remove warning about fbCompositeTrans_0888xnx0888 not
	being tested on big-endian, it's not helpful at this point.

	* src/pixman-remap.h: Only define _cairo_pixman_have_mmx for fbHaveMMX
	when the symbol will actually exist.

2005-08-21  Billy Biggs  <vektor@dumbterm.net>

	Fix for bug #4140:

	* src/icrect.c: (pixman_fill_rect_8bpp): Dereference the pixel value
	correctly on big endian systems.

2005-08-18  Billy Biggs  <vektor@dumbterm.net>

	* src/fbmmx.c: (mmxCombineMaskU), (mmxCombineOverU): Special case
	alpha values of 0 and 0xff.
	(fbCompositeSrc_8888x8888mmx): Add an MMX implementation for
	a common operation when using pixman.

	transforms so we can avoid doing the expensive 64-bit math.
	Unroll the bilinear interpolation loops for an extra boost.

2005-08-18  Billy Biggs  <vektor@dumbterm.net>

	* src/fbmmx.c: (fbCompositeSolidMaskSrc_nx8x8888mmx): For the source
	operator, the output should be cleared if the mask is zero.  This
	fixes the MMX code to match the fbcompose code.

	* src/fbpict.c: (pixman_composite): Fix a logic mistake that caused
	the MMX functions not to be used in many cases.

2005-08-17  Billy Biggs  <vektor@dumbterm.net>

	* src/pixman-remap.h: Only mangle exported symbols.  This is
	sufficient and makes debugging a lot easier.

2005-08-16  Billy Biggs  <vektor@dumbterm.net>

	* src/Makefile.am: Fix a typo in the last commit.

2005-08-16  Billy Biggs  <vektor@dumbterm.net>

	* src/Makefile.am: Split the MMX code into a separate libtool
	library to avoid applying the MMX CFLAGS to all of the pixman
	code.  Idea and code from Owen Taylor.

	* src/pixman-remap.h: Update the mangling header file to include
	the MMX symbols.

	* src/iccompose.c: Remove iccompose.c, replaced by fbcompose.c.

	* src/fbpict.h: Add a slightly-trimmed version of fbpict.h from
	xserver/fb to make the port smaller and cleaner.
	* src/ic.c: Use the redundant fbpict.h defines and add in the
	struct for indexed colour support.
	* src/icimage.h: Remove defines now in fbpict.h.
	* src/pixman-xserver-compat.h: Add some constants and types
	required by fbcompose.c

	* src/Makefile.am: Add fbcompose.c and fbpict.h, remove iccompose.c.

2005-08-10  Keith Packard  <keithp@keithp.com>

	* src/pixregion.c: (pixman_region_union_rect):
	Union with empty rectangle should yield SUCCESS, not FAILURE

2005-08-06  Jeff Muizelaar  <jeff@infidigm.net>

	* src/iccompose.c: (fbCombineMaskAlphaC), (fbCombineAtopC),
	(fbCombineXorC), (fbCombineSaturateU), (fbCombineSaturateC),
	(fbCombineDisjointGeneralC), (fbCombineConjointGeneralC):
	Fix problems in render fb implementation found by rendercheck:
	- 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.

	From anholt.


2005-08-06  Jeff Muizelaar  <jeff@infidigm.net>

	* src/iccompose.c: (fbFetch_r8g8b8):
	Temporarily disable the 24bpp WORKING_UNALIGNED_INT because of a crash
	when using electric-fence when accessing hte last pixel of a drawable
	(last pixel is 3 bytes, read it as a 4 byte word, and you're reading one
	 extra pixel, which doesn't normally matter, but does in a few rare cases).
	Should be easy to work around, but that will come later.

	From jaymz

2005-08-05  Jeff Muizelaar  <jeff@infidigm.net>

	* src/pixman-xserver-compat.h: Fix fbGetDrawable

	Patch from Billy Biggs <vektor@dumbterm.net>.

	(fbCompositeTrans_0565xnx0565), (fbCompositeTrans_0888xnx0888),
	(fbCompositeSrcSrc_nxn), (pixman_composite):
	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.

	From Keith Packard.

2005-08-01  Billy Biggs  <vektor@dumbterm.net>

	* src/fbedge.c: (clip255), (add_saturate_8),
	(fbRasterizeEdges8):  Optimize spans where the same value is
	being added to multiple pixels.  This improves the speed of
	rasterizing wide trapezoids.

	* src/icint.h: Add an INLINE macro that matches the one from
	fbpict.h in xserver/fb.

	Begin merging in newer fb code.
	
	The code comes from keithp:
	  Initial import of Composite extension along with
	  name change from Apportion.
	  Added some accelerated code to fbpict to make this initial
	  hack a bit faster.  "real" extension bits to follow.

	* src/pixman.h: Use 32-bits for pixman_bits_t, even on 64-bit
	platforms. This should fix bug #2335 as well as rendering problems
	seen on 64-bit platforms.

2005-01-21  Carl Worth  <cworth@cworth.org>

	* NEWS: Add notes for snapshot 0.1.3.

	* configure.in: Increment version to 0.1.3

	* RELEASING: Add reminder to diff pixman.h to look for API changes
	since the last snapshot.

	* src/Makefile.am (libpixman_la_SOURCES): Add missing files to
	satisfy make distcheck.

	* Makefile.am (RELEASE_UPLOAD_DIR): Update for changed www
	directory on server.

	* src/pixman-xserver-compat.h): Add pixman-xserver-compat.h, (that
	was supposed to go in a couple of commits ago).

	* src/fbedgeimp.h (rasterizeEdges): Avoid buffer ovverrun when
	trapezoid's right edge is on a pixel boundary.

	* src/ictri.c (IcRasterizeTriangle): 
	* src/ictrap.c (pixman_composite_trapezoids): Switch to use new
	fbRasterizeTrapezoid. Gut old IcRasterizeTrapezoid
	implementation. Remove lots of code, (and all the bugs with it).

	* src/icint.h: Replace IcRasterizeTrapezoid with
	fbRasterizeTrapezoid. Add a couple of missing typedefs.

	* src/renderedge.h: 
	* src/renderedge.c (RenderLineFixedEdgeInit): 
	* src/fbtrap.c: 

	* src/fbedge.c: Minor changes to allow things to compile within
	libpixman tree, (replace xserver include directives with
	pixman-xserver-compat.h and sprinkle a few const qualifiers).

	* src/Makefile.am (libpixman_la_SOURCES): Add sources for new
	point-sampling rasterization.

	* src/fbtrap.c: Merge in changes from xserver, (mostly just
	whitespace).

	* src/renderedge.c:
	* src/renderedge.h: Add pristine files from the X server
	containing Keith's newer point-sampling implementation of
	trapezoid rasterization. The plan is to munge these files as
	little as possible to make them work within libpixman, (so that it
	will be easier to share patches between libpixman and the X
	server).
	
2005-01-13  Carl Worth  <cworth@cworth.org>

	* src/ictrap.c (IcRasterizeTrapezoid): Force alpha to 0 when the
	left edge is entirely above top. (This is a workaround for some
	bizarre edge effects in the current algorithm).
	(IcRasterizeTrapezoid): Fix the above correction so that it
	doesn't force 0 alpha when the left edge is positioned above but
	slopes so as to contain some of the pixel.

2005-01-07  Carl Worth  <cworth@cworth.org>

	* src/icrop.h: 
	* src/icint.h: Restore extern tag for variable declarations,

	* src/Makefile.am (INCLUDES): Add the following warnings when
	compiling with gcc: -Wall -Wpointer-arith -Wstrict-prototypes

	-fno-strict-aliasing

	* src/icrect.c (pixman_color_rects): Fix to actually call
	pixman_fill_rect_32bpp in the 32 bpp case. Thanks to
	TOKUNAGA Hiroyuki <tkng@xem.jp>.
	(pixman_fill_rect_8bpp, pixman_fill_rect_32bpp): Fix typo in
	naming: bbp -> bpp.

2004-12-20  Alexander Larsson  <alexl@redhat.com>
