Backwards incompatible (API deletions or changes)
-------------------------------------------------
PDR C	cairo_surface_finish, cairo_surface_flush
PDR C	A hidden offset for the xlib backend
PDR C	Consistent error handling for all objects
PDRTC	Split cairo_format_t (see below for details)
P---C	Remove cairo_status_string in favor of cairo_status_to_string

Details on some of the above changes
------------------------------------
* cairo_text_glyphs:

	It would function as a sort of bridge between the toy and the
	real text APIs:

	>       void
	>       cairo_text_glyphs (cairo_t *cr, const unsigned char *utf8,
	>                          cairo_glyph_t *glyphs, int *num_glyphs);
	>
	> with num_glyphs as an input-output parameter. The behavior of this
	> function would be such that calling:
	>
	>       cairo_text_glyphs (cr, string, glyphs, &num_glyphs);
	>       cairo_show_glyphs (cr, glyphs, num_glyphs);
	>
	> would be equivalent too:
	>
	>       cairo_show_text (cr, string);
	>
	> as long as the original size of glyphs/num_glyphs was large
	> enough.

* support for custom caps:

  It would be nice if the user had a mechanism to reliably draw custom
  caps. One approach here would be to provide the coordinates of the
  butt cap faces so that the user can append seamless caps to the
  current path. We may also need to provide the coordinates of the
  faces of every dash as well.

Changes that do not affect the public API
=========================================
* Fix clipping to work for all operators. The equation we have come up
  with is:

	((src Op dest) In clip) Add (dest Out clip)

* Change stroke code to go through one giant polygon. This will fix
  problems with stroking self-intersecting paths.

* Fix the intersection problem, (see reference to Hobby's paper
  mentioned in cairo_traps.c).

* Implement dashing for cairo_curve_to.

* Stroking closed, degenerate paths should still draw caps.  Round
  caps are easy; square should probably draw an axis-aligned square.

* Should add geometry pruning as appropriate.

* Verification, profiling, optimization.

	centi_unfinished.svg may provide a good test case.
