You said last night that it's inconsistent with
cairo_new_path;cairo_fill.  I took your word last night but sounds wrong
to me now too.  cairo_new_path;cairo_fill should fill nothing, and
cairo_new_path;cairo_clip should clip everything out.  The logic is
obvious: you start with the empty set and add regions using various path
construction functions.

There's always cairo_reset_clip.


So yes, I guess this was a non-issue.  Maybe we need tests for both fill
and clip if we don't already have.
