2012-06-15image: Fix up glyphs compositingChris Wilson1-36/+24
Jose Dapena Paz reported an assertion following the uninitialised status value being returned. Also the function failed to free its allocations. Based on a patch by Jose Dapena Paz <jdapena@igalia.com>.

2012-06-14subsurface: Disable subsurface-set-snapshot as it creates a ref cycleHenry Song1-0/+6
_cairo_surface_subsurface_set_snapshot () sets the subsurface as the snapshot of its target. This creates a reference cycle (as the target is already referenced by the surface) and thus a memory leak (assuming the likely case that user doesn't call finish). Test case: subsurface-similar-repeat. So make this call as a no-op for the time being until the bug is fixed.
2012-06-14quart-image: Fix compilationAndrea Canciani1-1/+1
quartz-image uses _cairo_surface_is_image(), which is now declared in cairo-image-surface-inline.h. Fixes: cairo-quartz-image-surface.c: In function 'cairo_quartz_image_surface_create': cairo-quartz-image-surface.c:312: error: implicit declaration of function '_cairo_surface_is_image' cairo-quartz-image-surface.c:312: warning: nested extern declaration of '_cairo_surface_is_image'
2012-06-09Use the new pixman_glyph_cache_t API that will be in pixman 0.28.0Søren Sandmann Pedersen5-249/+121
This new pixman API allows glyphs to be cached and composited in one go, which reduces overhead compared to individual calls to pixman_image_composite_region32(). Notes: - There is an explicit call to _cairo_image_scaled_glyph_fini(). This could instead be done with a private, but I chose not to do that since we don't need to store any actual data; we only need notification when the glyph dies. - The slowdown in poppler-reseau is real and stable across runs. I'm not too concerned about it because this benchmark is only one run and so it is dominated by glyph cache setup costs and FreeType rasterizing.

2012-06-08polygon-reduce: Reduce broken stopped-edge continuationChris Wilson1-105/+52
This is hopefully a lesser used path and the attempted optimisation to continue a stopped edge with a colinear stopped edge highly unlikely and lost in the noise of the general inefficiency of the routine. As it was broken, rather than attempt to rectify the "optimisation" remove it.

2012-06-08spans-compositor: After polygon intersection the fill rule is always non-zeroChris Wilson1-0/+2
As it turns out due to the rules of polygon intersection, there is never any overlapping spans so the choice is arbitrary. However, lets be consistent with the rest of the code. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-06-01image: Fix bugs related to glyph mask creationSøren Sandmann Pedersen1-2/+2
In addition to fixing a bug 7d8d98b91ccf7165be853c36e6d5ef releated to expanding a8 glyphs into a8r8g8b8, this commit also added an optimization where if the first glyph had format a8r8g8b8, the mask was created in this format from the beginning instead of later converting from a8 to a8r8g8b8. However, the optimization had two bugs in it: (1) The computed stride was 3 * width, not 4 * times width, and (2) In the case where the mask was allocated on the stack, it was allocated as PIXMAN_a8 and not a8r8g8b8. The commit fixes both bugs.

2012-05-31gl: Do correct translation and lerp in gl-traps-compositor.Chuanbo Weng1-8/+14
Coordinate translation is necessary in composite_boxes(), composite() and composite_traps(). The translation value should set to correct value in traps_to_operand(). Also fix the bug in lerp().
2012-05-31image: Upconvert glyphs through a WHITE source when adding to the glyph maskChris Wilson1-19/+55
We need to scale the channels of the glyph into the destination (and indeed expand a8 into a8r8g8b8) when adding into the mask. Normally we have matching formats for the glyph surfaces and the temporary mask, for which we can continue to take the faster path.

2012-05-30configure.ac: remove annoying change of INSTALL fileYuanhan Liu1-1/+1
Every time we run ./autogen.sh, the INSTALL file would be replace by /usr/share/automake-1.11/INSTALL, which changes the file. This is very annoying since it messes up the result of 'git diff' and git always wants to commit it. Declare it as foreign would fix this annoying issue. Since it's not a GNU project, it makes sense to do so. Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com>

Use _cairo_gl_operand_copy to do the operand copy instead of by something like *operand = surface->operand. This would fix a crash introduced by operator-source test case, which forgot to do reference while copying operand but did dereference while destroying surface at combine_clip_as_traps().

2012-05-26surface: Use the internal map/unmapAndrea Canciani6-44/+46
In many places Cairo maps/unmaps surfaces to perform operations on the raw image, but it doesn't care about the format being invalid. All of these are appropriate users of _cairo_surface_map_to_image().
2012-05-26surface: Only use non-NULL extents for internal mappingAndrea Canciani2-4/+14
_cairo_surface_map_to_image() requires the input extents to be non-NULL.
2012-05-26surface: Make backend-specific map/unmap functions symmetricAndrea Canciani11-47/+48
Map allocates a surface. Symmetrically, unmap should destroy it.
2012-05-26surface: Make map_to_image return cairo_image_surface_t*Andrea Canciani17-39/+51
This makes it easier to check that the funciton is returning the correct type of surfaces.
2012-05-26surface: Define private map/unmap functionsAndrea Canciani4-73/+222
Cairo backends often need to map/unmap to a raster surface but they don't care about the pixel format, as Pixman will be doing the format handling. Cairo users cannot know how to access the raw data if the format is invalid. The two different scenarios call for different guarantees on the returned surface. The private map/unmap functions also makes it possible to simply return the status upon unmapping.

2012-05-26build: Do not replace existing filesAndrea Canciani1-1/+1
The existing INSTALL file is currently being replaced at every autogen.sh run with the default one. This is not desired, because INSTALL contains some cairo-specific information.
2012-05-26build: Allow autogen-eration on systems without GTK-docAndrea Canciani1-3/+3
The autogen.sh script fails if it cannot run gtkdocize. The absence of this command should not cause cairo builds to fail, it should only prevent the build of its documentation.
