Yes, fair enough.

If we're going to have a getter like _get_patch_count that will work on
"mesh patterns" but not on other types of patterns, then it really would
be more consistent with the cairo API naming for that to be:


I think my earlier comment about liking the function name without "mesh"
at all was only in preference to the version with cairo_pattern_mesh
which is backwards.

So cairo_mesh_pattern_get_patch_count (and friends) should satisfy the
original point Behdad made about the functions needing to be
namespace-restricted to mesh patterns, and should do it in a way that's
consistent with the rest of the cairo API naming conventions.
