Fixes up src coords and width/height before calling AlphaBlend/BitBlt; it's
an error to try to use a region that extents outside of the source surface
as a source DC.
Doesn't repair the extra region relative to the operator -- e.g. regions
outside of an ARGB source surface with SOURCE operator should be cleared
to fully transparent black in the destination.

Adds cairo_win32_surface_create_dib() for creating a win32 DIB-backed
surface with a particular format. Also exposes
cairo_win32_surface_get_dc() to obtain the DC of a win32 surface.

mark_dirty will force cairo to set its own clip the next time the cairo clip
is applied after mark_dirty; otherwise we run the risk of cairo's cached
clip and the device clip getting out of sync if any clip-related functions
are used on the native device back-end.

This also has the benefit of preserving the API that has been in place for PS/PDF surface since the (experimental) stuff in 1.0.0.
Track API change.
Continue testing PS/PDF surfaces in the CAIRO_CONTENT_COLOR mode but do it by rendering to an intermediate similar surface rather than constructing the target surface differently.
Add documentation. Add a cairo_content_t argument to PDF surface constructors.
Add documentation. Add a cairo_content_t argument to PS surface constructors.
Track changes in PS/PDF surface constructor API.
The PS/PDF backends don't allow a content to be passed in right now, so they fail against the rgb24 tests, but the trivial addition to the constructors will allow them to pass all tests with both content values.
And new constructors (currently internal only) to create an image surface with a cairo_content_t rather than a cairo_format_t.
Add a cairo_content_t argument to the constructor.
Add a cairo_content_t to the constructor and use this content value when constructing intermediate image surfaces in acquire_source, show_page, copy_page, and snapshot.
Add image flattening by compositing over white, as is done in cairo-ps-surface.c.
Track changes to cairo-paginates-surface which now requires a cairo_content_t value (no change to public PS/PDF constructors yet).
Track change in meta-surface and paginated-surface interfaces by now accepting a cairo_content_t rather than a cairo_format_t.
Ignore new output files (argb32 from pdf and ps as well as rgb24 from test-fallback, test-meta, and test-paginated).
Add new utility for flattening PNG images in order to generate the -argbf-ref.png images.
Add image_diff_flattened for comparing flattened output from PS and PDF backend with ARGB reference images by first blending the reference images over white.
Get rid of conditional, format-specific background-color initialization before running tests. Now uses ARGB(0,0,0,0) in all cases. Switch from specifying tests with a format value to specifying tests with a content value. Add support for a 'fake' COLOR_ALPHA_FLATTENED content for testing the PS and PDF output against a flattened version of the argb32 reference images (first blended over white).
Track change in cairo_ps_surface_create (now requires cairo_content_t value).
Adjust tests that draw in default (black) to first paint white so that the results are visible.
Adjust ARGB32 reference images for new white background for changed tests.
Adjust RGB24 reference images for new black background due to changed initialization (and the tests themselves being unchanged).
Fix broken implementation of copy_page in the paginated surface by hiding it from the target surface which sees only show_page operations. (It's hard to do better than that unless we can guarantee thathe subsequent page won't trigger any image fallbacks.)
Move the Y-axis-flipping to be on a per-page basis (as it was before and as it must be). Put page number back in, (still missing th number of pages from the header).
Add multi-page output for better testing.
Switch from ARGB32 to RGB24 for intermediate image surface since that's all that the current users of cairo_paginated_surface support anyway.
Switch cairo_ps_surface_t over to use the new cairo_paginated_surface_t. This drastically simplifies the implementation, but temporarily puts the PostScript output back into the land of one-image-per-page. To be fixed soon though with improvements to cairo_paginated_surface_t. Everything still passes the test suite which is good. The test suite currently does no testing of multi-page output, which is quite bad.
Add new functions needed by users of cairo_paginated_surface_t.
Always snapshot a paginated surface to an image surface, rather than a surface similar to the target. We do this since paginated target surfaces are allowed to not be complete surfaces, (such as not implementing acquire_source_surface).
Switch the implementation of cairo_pdf_surface_t to use cairo_paginated_surface_t. For now this means that all PDF output is fallback images, but this can change incrementally as we go forward.
If the destination surface is a quartz surface, get the clip mask from it.
Added.
Keep a copy of the clip mask around.
(_cairo_surface_is_quartz): New function which determines if a given surface is a quartz surface.
Change the paginated surface to force all output to come from an image surface (to be refined incrementally as we hook real surface backends up to it).
Implement copy_page for paginated surface. Fix show_page to destroy the meta-surface and create a new one.
Change these functions to advertise when they are not supported, so that _cairo_paginated_copy_page can implement things differently depending on whether or not it is personal.
Check return values from _cairo_surface_show/copy_page.
Throw away old gradient code from within cairo-pattern.c in favor of using new support in pixman for gradients.
Update reference images for all tests involving gradients since the gradient output has changed slightly.
Try to recover a standard cairo_format_t from given pixman format masks, so that various things that only work with a standard format work correctly.
Remove cairo_glitz_surface_write_to_png, replace with generic cairo_surface_write_to_png (since it works with image-surface create_with_masks fix)
