66e69f18ec Perform copy and reference in a single step.

9796a54fa1 Style fix: test-and-bail rather than making the working body conditional.

9341c254a0 Rename old, rarely used _cairo_array_append to _cairo_array_append_multiple. Add much more common _cairo_array_append. Fix both to return a cairo_status_t. Remove undocumented code to allow a non-copying append when elements is NULL, (let's not encourage unintialized data, shall we?) 
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.

39eca22bfe Rework support in the surface backend for the five basic drawing operations (paint, mask, stroke, fill, and show_glyphs). Now, all 5 operations have backend functions, and all use a consistent convention for argument naming and ordering. The old fill_path has been replaced with a new fill. The old show_glyphs function was recently renamed to old_show_glyphs and has not yet been ported to the new show_glyphs, (so all backends have a NULL show_glyphs function). In fact, of the 5 new backend functions, fill is the only one that has an implementation in any backend. As part of this cleanup a new cairo_stroke_style_t object is introduced to capture the many settings unique to the stroke operation, (line_width, line_cap, line_join, miter_limit, dash, num_dashes, and dash_offset). 
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.

4f97b2edb5 New function to create a snapshot copy of a pattern. 
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.

ea7ac21d3b Add a "nearest" extend mode, where the closest pixel is repeated for pixels outside of the source area. Note that for gradients, applications which had explicitly set a repeat mode of NONE will now need to change to use NEAREST to get the same behaviour. 
Split CARIO_EXTEND_DEFAULT to indicate defaults for surfaces and gradients. The default for gradients is still the NEAREST beaviour.
Support the NEAREST mode, change NONE to be TRANSPARENT.
Update the extend mode code to use the pixman support.
Handle NEAREST, note that support for NONE is not yet handled for gradients.
Add a check for NEAREST but don't do anything useful.
