Use _cairo_fixed_to_double and _cairo_double_to_fixed when converting between double and 16.16 fixed point. These functions round nicely, and solve some inconsistencies in rendering between my PPC and x86 machines. Thanks to Owen Taylor for suggesting the fix.
The above change does affect linear gradients slightly, but it seems worth it. Update the reference images to follow.
Use pointer comparison for coincident points to ensure a well-defined ordering, and avoid setting discard on both points. This fixes problems with my Mac's implementation of qsort. Final patch by Bertram Felgenhauer.
Update reference images after the change.
Update from gtk-doc CVS, bringing in some minor output changes. (Eliminate the *** from the messages that don't indicate errors.)
Use += for EXTRA_DIST, since gtk-doc.make already defines it.
Disable xlib tests on X servers without the Render, since they currently just crash there. A better long-term fix would be to do some useful tests in this case. Thanks to Tim Mooney.
Improve the performance of png reading by adding special cases for fully transparent and fully opaque alpha, and using the standard optimization for 8-bit division by 255.
Add an INLINE macro for gcc.
Don't change the status value if it already holds an error. This avoids destroying "first error" information and also avoids attempting to write read-only data, (eg. from nil objects).
Don't set an error on the same object if it is in an error state to begin with, just return immediately. This is intended to reduce (eventual) error prints to the first cause of an error for any given object, instead of a continual spew.
Adjust negative offsets up to their equivalent positive value. Add error checking for dash values, (must each be non-negative and must not be all zero).
Add documentation.
Add new CAIRO_STATUS_INVALID_DASH.
Add dash-offfset-negative test from Owen.
churn
New function to return the current nil pattern depending on the status.
Add missing early bailout on surface->status with error propagation to the pattern.
Related cleanups for cairo_pattern_t:
Don't check other->status since this is a static function.
Add missing early bailout on other->status.
Cleanup identifier names.
Track rename of nil patterns.
Don't call _cairo_error for pre-existing errors.
Take care to initialize some fields to that _cairo_pattern_release_surface will work even after an error.
Track rename of cairo_solid_pattern_nil to cairo_pattern_nil.
New test to ensure that a file-not-found error will propagate from a surface, through a pattern, and onto a cairo_t.
CLEAR and SOURCE are now bounded.
Assert that SOURCE and CLEAR aren't passed to these functions.
Assert that SOURCE and CLEAR aren't passed to these functions when there is a mask.
Do fixups for SOURCE and CLEAR as well as unbounded operators, since in the absence of a mask, we need SOURCE to work correctly (don't care about CLEAR)
_cairo_ft_font_show_glyphs) Consistently use CLEAR/TRANSPARENT (source doesn't matter) rather than SOURCE/TRANSPARENT when clearing rectangles.
src/cairo-xlib-surface.c src/cairo-surface.c: Use IN rather than SOURCE as an example of an unbounded operator in docs.
Remove CLEAR/SOURCE columns since they are no longer unbounded.
test/operator-clear.c test/operator-source Makefile.am: Add targetted tests of CLEAR/SOURCE.
Include the version number, along with the title, in a bookinfo section.
Add the version.xml.in to the dist.
Ignore version.xml.
Generate doc/public/version.xml.
Don't call _cairo_ft_unscaled_font_init_key in the from_face case, just clear filename and id instead. Initialize unscaled->base first so that initialization order matches the structure declaration order.
Fix to accept a NULL string and hash it identically to a zero-length string.
Add a test that calls cairo_ft_font_create_for_ft_face to demonstrate bug #4110.
