GTK+ 2.10 - http://www.gtk.org/plan/2.10/
------------------------------------------
The 2.10 release is scheduled for May 2006, (to be in time for GNOME 2.16).
Satisfying GTK+ 2.10 well requires releasing cairo 1.2 with good
printing support, (good PS/PDF output, per-page sizing and layout,
etc.) sometime in April 2006.
GNOME 2.16 (http://live.gnome.org/TwoPointFifteen)
--------------------------------------------------
With cairo 1.2 already part of GTK+ 2.10, we want to make sure that
the cairo used in GNOME 2.16 is as good as possible. The final date
for 2.16 is September 6, 2006 but the deadline of interest to us is
the tarball due date for next beta (2.16.0 Beta 2 -- 2.15.91) which is
August 7, 2006.

Themes and Schedules
====================
cairo-1.2 (April 2006): Better printing
- Supported PS/PDF output

cairo-1.2.2 (August 7, 2006): Fix the bad bugs in 1.2.0
- Fix failure on BGR X servers
- Fix the disappearing text bugs
cairo-1.4 (October 2006): Better performance
- New tessellator
- New rasterization
- Finer-grained fallbacks for PS/PDF

✓ PDF: minefield page one is falling back unnecessarily
✓ should be possible to draw caps with degenerate paths
cairo 1.4.0 ideas (think performance!)
======================================
Implement framework for performance regression testing
✓Fix memory leaks
✓1. Ensure 'make check-valgrind' passes with no leaks (mostly done)
Investigate "low-hanging fruit" identified by David Turner (write test case for each)
Bugs that might already be fixed anyway
---------------------------------------
6617 With cairo 1.0.4 some text just disappears
Look into speeding up pixman gradients
Bugs that won't be fixed
------------------------
Look into improving text positioning/placement on ARM (with no hardware floating-point)
Look into speeding up dashing used for GTK+ focus rectangle
Look into other GTK+ performance regressions as identified on performance-list
xlib backend
Switch to server-side gradients for xlib backend
Fix X server to make server-side gradients faster
Switch to using XRenderAddTraps rather than XRenderCompositeTrapezoids
Implement a non-trapezoid based rasterizer for use with xlib and other backends
Cull geometry outside clip region bounds
New tessellator
Unscheduled stuff we'd like to get to at some point
===================================================
Fairly severe bugs
6806 cairo 1.0.4 crash progressbar in window
PDF: minefield shows too-tiny bitmapped fonts in image fallback
PDF: minefield shows strangely hinted glyph shapes (only without truetype subsetting)
PDF: minefield has broken selection (only with truetype subsetting code)

4863 stroking problems with wide dashed lines

✓c. Translucent objects (using OVER) are also native
✓d. Text output uses PDF font features (type 3)
✓Bug fixes with API implications
✓ cairo_{ps,pdf}_surface_set_dpi have no effect (replace with cairo_surface_set_fallback_resolution)
✓ cairo_set_line_width semantics (that's not a bug, it's a feature)
✓Bug fixes (For each XXXX, see: https://bugs.freedesktop.org/show_bug.cgi?id=XXXX )
