cairo_image_surface_create should clear image: NOTABUG. The user can clear if desired, and cairo clearing unconditionally would be performance overhead). cairo_clip is really slow: FIXED/COVERED. Since the time this entry was added we've got rectangular, pixel-alignend clipping optimized. And there's a bug in bugzilla (https://bugs.freedesktop.org/show_bug.cgi?id=4191) for optimizing IN. self-intersecting path is wrong: COVERED by test/self-intersecting.c. Cairo is crashing Xnest: NEEDINFO. Is this still happening? Xfake has been working quite well for a very long time now. font-size=0 in SVG does bad things: FIXED.

cairo-xlib-surface needs to do the Xlib register extension hack so
|
|
that it can listen for a Display close event. When it gets that, it
|
|
needs to run through its caches and eliminate anything associated with
|
|
that display.

The caches need to be invalidated at font destruction time.

The polygon tessellation routine has problems. It appears that the
|
|
following paper has the right answers:

[Hobby93c] John D. Hobby, Practical Segment Intersection with
|
|
Finite Precision Output, Computation Geometry Theory and
|
|
Applications, 13(4), 1999.
|
|
|
|
Recent improvements to make the intersection code more robust (using
|
|
128-bit arithmetic where needed), have exposed some of the weakness in
|
|
the current tessellation implementation. So, for now, filling some
|
|
polygons will cause "leaking" until we implement Hobby's algorithm.

cairo_show_text is not updating the current point by the string's advance values.

ref_counts will go negative if destroy is called with ref_count ==
|
|
0. We noticed this in cairo_surface.c but it likely happens in several
|
|
places.
