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.

Change surface backend create_similar call to accept a cairo_content_t rather than a cairo_format_t.
Fix all calls into create_similar to pass a cairo_content_t rather than a cairo_format_t.
Remove obsolete comment.
Make a couple of stylistic changes and add _cairo_output_stream_write_hex_string.
Add _cairo_surface_intersect_clip_path so we can replay path clipping.
Also in this patch is a change to the xlib surface that creates two separate Pictures, one for source and one for destination operands which separates the source clipping from destination clipping. Cairo now specifies that sources are never clipped by any clipping applied to them as destinations.
Move cairo_clip_t (renamed from cairo_clip_rec_t) from cairoint.h to cairo-gstate-private.h. Eliminate stack of clip state from surfaces. Add new surface clipping API.
Manage clip objects entirely within the gstate, loading the whole thing into the surface just before drawing.
Source surfaces need not have clipping modified as the surface interface now specifies that source surfaces are always unclipped.
Eliminate nested clipping contexts, leaving clip management entirely to the gstate. Create new clip API for the gstate which uses per-surface serial numbers to match gstate clipping against current surface clipping values.
Surfaces no longer track clipping regions at all, so the old _cairo_surface_get_clip_extents has been replaced with _cairo_surface_get_extents. For PDF/PS surfaces, this function is expected to return a rectangle covering the entire fixed point coordinate space to leave rendering unclipped by the surface.
Region clipping capability is now signalled by a non-NULL function pointer in set_clip_region.
Each surface now contains two Pictures, one for source and one for destination operands so that source operands are never clipped by destination clipping.
