        Big change to the test infrastructure and supporting
        internals. The goal now is to test both a COLOR_ALPHA and a COLOR
        content for each surface backend, (since the semantics are
        different and we probably need to support both in each backend.

        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.

        * src/cairoint.h:
        * src/cairo-image-surface.c:
        (_cairo_image_surface_create_with_content),
        (_cairo_image_surface_create_for_data_with_content),
        (_cairo_image_surface_create_similar): And new constructors
        (currently internal only) to create an image surface with a
        cairo_content_t rather than a cairo_format_t.

        * src/cairo-meta-surface-private.h:
        * src/cairo-meta-surface.c: (_cairo_meta_surface_create),
        (_cairo_meta_surface_create_similar): Add a cairo_content_t
        argument to the constructor.

        * src/cairo-paginated-surface-private.h:
        * src/cairo-paginated-surface.c: (_cairo_paginated_surface_create),
        (_cairo_paginated_surface_acquire_source_image), (_paint_page),
        (_cairo_paginated_surface_show_page),
        (_cairo_paginated_surface_snapshot): 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.

        * src/cairo-pdf-surface.c: (emit_image_rgb_data),
        (_cairo_pdf_surface_composite_image), (emit_surface_pattern): Add
        image flattening by compositing over white, as is done in
        cairo-ps-surface.c.

        * src/cairo-ps-surface.c:
        (_cairo_ps_surface_create_for_stream_internal),
        (cairo_ps_surface_create), (cairo_ps_surface_create_for_stream):
        * src/cairo-pdf-surface.c:
        (_cairo_pdf_surface_create_for_stream_internal),
        (cairo_pdf_surface_create_for_stream), (cairo_pdf_surface_create),
        Track changes to cairo-paginates-surface which now requires a
        cairo_content_t value (no change to public PS/PDF constructors
        yet).

        * src/test-fallback-surface.h:
        * src/test-fallback-surface.c: (_test_fallback_surface_create),
        (_test_fallback_surface_create_similar):
        * src/test-meta-surface.h:
        * src/test-meta-surface.c: (_test_meta_surface_create):
        * src/test-paginated-surface.h:
        * src/test-paginated-surface.c:
        (_test_paginated_surface_create_for_data): Track change in
        meta-surface and paginated-surface interfaces by now accepting a
        cairo_content_t rather than a cairo_format_t.

        * test/.cvsignore: Ignore new output files (argb32 from pdf and ps
        as well as rgb24 from test-fallback, test-meta, and
        test-paginated).

        * test/Makefile.am:
        * test/png-flatten.c: (main): Add new utility for flattening PNG
        images in order to generate the -argbf-ref.png images.

        * test/buffer-diff.c: (image_diff_flattened):
        * test/buffer-diff.h: 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.

        * test/cairo-test.c: (_cairo_test_content_name),
        (create_image_surface), (create_test_fallback_surface),
        (create_test_meta_surface), (create_test_paginated_surface),
        (test_paginated_write_to_png), (create_cairo_glitz_glx_surface),
        (create_cairo_glitz_agl_surface), (create_cairo_glitz_wgl_surface),
        (create_win32_surface), (create_xcb_surface),
        (create_xlib_surface), (create_ps_surface), (create_pdf_surface),
        (create_svg_surface), (cairo_test_for_target),
        (cairo_test_expecting): 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).

        * test/multi-page.c: (main): Track change in
        cairo_ps_surface_create (now requires cairo_content_t value).

        * test/caps-joins.c: (draw):
        * test/caps-sub-paths.c: (draw):
        * test/dash-caps-joins.c: (draw):
        * test/dash-offset-negative.c: (draw):

        (black) to first paint white so that the results are visible.
