Add missing glue to hook up PS backend with new meta-surface support for the 5 basic drawing operations. Currently, this forces image fallbacks for all operations.
Switch from gs device of pngalpha to png16m which for some reason gives the correct result for nil-surface now, while pngalpha does not.
Key off of N_OPERATORS as the loop control for easier trimming down of this test case when debugging.
Rename stroke_style parameter to style in backend->stroke parameter list.
Remove PS-specific reference images for many tests which are now using more fallback paths than before.
Remove size for _cairo_meta_surface_create. It is no longer needed now that get_extents is not a required backend function.
Track change in cairo_meta_surface_create no longer requiring a size
Qualify the glyphs argument to backend->show_glyphs as const.
Whitespace style cleanup.
Add new function to be used instead of the abuse of pasing data=NULL to cairo_pdf_ft_font_write.
Just return a status now instead of a pointer to the written buffer, since cairo_pdf_ft_font_allocate_write_buffer should now be used instead when a pointer is needed.
Switch to use cairo_pdf_ft_font_allocate_write_buffer.
Fix use of uninitialized status value.
initialization just to keep the compiler quiet about possibly uninitialized variables.
Cleanup to not rely on undocumented copy-avoidance in _cairo_array_append.
Track change in number of arguments and return value of _cairo_array_append.
Track changes in surface backend from fill_path to fill.
Track the new canonical argument naming and ordering for the 5 drawing operations.
Move various stroke style settings into new cairo_stroke_style_t.
Drop NULL fill_path backend function which no longer exists.
Remove pen_regular field from the gstate.
Move stroke fallback from gstate to surface where it belongs.
Eliminate dependence on cairo_gstate_t object.
Fix to include just cairo-clip-private.h rather than cairo-gstate.private.h.
Move mask fallback from gstate to surface where it belongs.
Temporarily export some previously private cairo_gstate functions, (soon to become private cairo_fallback functions).
Use fallbacks for any operation using a pattern other than a solid pattern, since it's the only type that will actually emit anything right now.
Add comments indicating these functions are not yet implemented.
Replace the surface->fallback_region with a page-level surface->fallback Boolean instead, since that's all it was being used as anyway.
Do nothing in the ps_output->fallback case.
Do nothing in the ! ps_output->fallback case.

Port code to use _init_pattern_with_snapshot rather than _cairo_pattern_init_copy for all source and mask patterns.
New function to create a snapshot copy of a surface (still preliminary---no support for meta-surfaces or any other surface for which acquire_source_surface will fail).
Add new surface->is_snapshot and initialize to FALSE.
Assert that none of these surface-modifying functions are ever called with a snapshot surface.
