Split off from _cairo_xlib_surface_create to avoid roundtrip when
size is already known.
(cairo_xlib_surface_create): Simplified to just call XGetGeometry
that defer to _cairo_xlib_surface_create_with_size. Add comment
about remaining roundtrip and possible plans to eliminate it later
with a new interface requiring width/height.

2004-12-02 David Reveman <c99drn@cs.umu.se>
* src/cairo_gstate.c (_cairo_gstate_clip): Revert the "return early"

NULL font.
2004-11-13 Carl Worth <cworth@cworth.org>

destroy the old font, (otherwise, if the same font was selected
twice in a row, a reference was lost to it, leading to assertion
failures).

loop-independence.
