No longer need to check for NULL after creating a pattern.
Propagate status errors from pattern->status to cr->status.
Originally 2005-05-08 Owen Taylor <otaylor@redhat.com>:
src/cairo-pattern.c src/cairoint.h: If allocation of pattern objects fails, return special static nil pattern objects.
If adding a color stop fails to allocate memory, set pattern->status. (And fix a memory leak.) Make public functions return when pattern->status is set, (and no longer return a cairo_status_t).
src/cairo-pattern.c src/cairo.h doc/public/cairo-sections.txt: Add cairo_pattern_status()
Check the status of gstate->source and of mask patterns passed in.
