coordinate space to the nominal pixels.
Treat more alpha values as translucent (up to 0.999)
Fix emit_image to actually use a temporary image when necessary.
Change PS coordinate space to match cairo (top-down), adjust PS output to use new space.
Find more cases where PS output was not supported and fall back to image surface.

scaled_font->backend->show_glyphs is needed.

system seen by the backend can differ from the nominal device coordinate space used by the application.
Useful for printer backends where the device coordinate space should be in pixels while the user visible device space is in points.
There is no API to set these values; the backends using this functionality should do that themselves before the first cairo_t is created.

Add test to verify that the current-point-advancing behavior of cairo_show_text is working.
Remove bug about cairo_show_text not advancing the current point.

Document the width and height parameters of cairo_xlib_surface_set_drawable().

Abstract the cap-addition code from the end of the stroke operation into a new _cairo_stroker_add_caps function.
Call the new _cairo_stroker_add_caps at the beginning of every move_to so that we get caps on every subpath and not just the last one.

New function to handle both calling FT_Done_Face on unscaled->face and decrementing font_map->num_open_faces.
Call new _font_map_release_face_lock_held as approporiate.
Assert that (font_map->num_open_faces == 0) when we're done, to help guarantee the bug is fixed.
Don't call FT_Done_Face anymore, instead assert that (unscaled->face == NULL) by the time this function is called.
Prefer TRUE/FALSE as values for cairo_bool_t have_scale.

Add target "zips" to create zip file based distribution for Win32.

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.

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 missing early bailout on other->status.

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.
