 Everything here is subject to change, but it is hoped that all of it
-will be useful. If you want to influence, please feel free to get

+cairo 1.4.4 (scheduled for 2007-04-09)
+======================================
+ • Mathias Hasselmann's "static region" patch series, (to be reviewed
+   by behdad, and performance tested by cworth)
 
-Additionally, people who are actively developing cairo itself should
-regularly update this document to reflect their current plans. If you
-don't want to see a particular release happen without some essential
-feature, then put that feature on the list and put your name next to
-it to indicate you are working on it.
+ • Chris Wilson's many recent cleanups, (to be reviewed by behdad and cworth)
 
-Targets
-=======
-Firefox 3.0 - http://www.mozilla.org/projects/firefox/roadmap.html
-------------------------------------------------------------------
-Firefox 3 (scheduled for early 2007?) is the first release expected to
-use cairo for all rendering. In the meantime, development builds using
-cairo are available. Satisfying firefox 3 well requiring releasing a a
-new version of cairo some months before the firefox 3 release data
-with much-improved performance.
-
-Gnome 2.18 - http://live.gnome.org/TwoPointSeventeen
-----------------------------------------------------
-Looks like early January would be a great time to get cairo 1.4 out.
-

- - [Bug 10150] Support inline with Sun Studio compiler
- - AltiVec patches
- - Kmaraas's warning cleanups
- - Mathias's Mutex cleanup patch
- - Update bindings chapter of documentation to reflect new APIs
+ • 10508 Painting regression in 1.4.x (cworth)
+

+   (choose one of the existing patches)
+
+ ✓ 10531 cairo nquartz backend floating point precision issues (bewins)
+
+cairo 1.4.x (not scheduled, may become part of 1.6)
+===================================================
+ • David Turner's cairo-ft rewrite. (behdad)
+
+ • Fix all remaining XFAIL failures from the test suite
+	a8mask has a patch available on the list
+
+ • Implement CAIRO_EXTEND_PAD for surface patterns
+
+ • Work around bug in X server causing extend-reflect test to hang it
+
+ • Eliminate problems with "unsupported image formats" for xlib,
+   (very frequently duplicated bug reports and a regression since
+   cairo 1.0.x apparently)
+
+	7735 cairo doesn't support 8-bit truecolor visuals
+	9993 Cairo fails with 555 X server visual
+
+ • Discard trapezoids that lie outside the clip region (cworth)
+
+ • Review and land AltiVec patches
+
+ • Update bindings chapter of documentation to reflect new APIs
    (get_reference_count() and user_data for all)
- - Work around bug in X server causing extend-reflect test to hang it
- - Fix a8mask (patch available)
- - Possibly remove pdiff
- - Make font backends separable from their native surfaces
 
-cairo 1.4.0 ideas (think performance!)
-======================================
-✓ Implement framework for performance regression testing
+cairo 1.6 (scheduled for July 2007, targeting firefox and GNOME)
+================================================================
+ • Change from 16.16 to 24.8 (or so) for fixed-point storage (cworth)
+
+ • Implement a faster lookup-table-based rasterizer (cworth)
+
+ • New cairo-xlib API to support IncludeInferior Pictures (see bug
+	10329 for one proposal --- perhaps do
+	cairo_xlib_surface_create_for_picture instead)
+
+ • Make cairo-quartz a supported backend (vlad)
 
- Investigate "low-hanging fruit" identified by David Turner (write test case for each)
+ • Make cairo-xcb a supported backend (Jamey Sharp)
 
-✓ Look into speeding up pixman gradients
+ • A significant improvement to pixman compositing code (jrmuizel)
+   jrmuizel's recent work and other ideas going on).
 
-✓ Look into improving text positioning/placement on ARM (with no hardware floating-point)
+ • User-font API (behdad, krh)
+	http://lists.freedesktop.org/archives/cairo/2007-February/009539.html
+	http://lists.freedesktop.org/archives/cairo/2006-May/006893.html
+	http://lists.freedesktop.org/archives/cairo/2006-May/006888.html
 
- Look into speeding up dashing used for GTK+ focus rectangle
+ • cairo_font_options_[gs]et_writing_mode()  (behdad)
+	http://lists.freedesktop.org/archives/cairo/2007-January/009372.html
 
-✓ Look into other GTK+ performance regressions as identified on performance-list
+ • cairo_font_metrics_t (behdad)
+	http://lists.freedesktop.org/archives/cairo/2007-January/009373.html
 
- 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
+ • New text API that allows for perfect text extraction in PDF (behdad)
 
- Implement a non-trapezoid based rasterizer for use with xlib and other backends
+ • Set PS Level for the PS backend (adrianj)
 
- Cull geometry outside clip region bounds
+ • EPS output from the PS backend (adrianj)
 
-✓ New tessellator
+ • API to allow enable/disabling certain subsetters (adrianj)
+	http://bugs.freedesktop.org/show_bug.cgi?id=8180#c28
+	This would also be useful feature to control via an environment
+	variable as it would allow the user to override the application
+	settings.
 
- Bugs to fix
- -----------
-   CAIRO_EXTEND_PAD is not implemented for surface patterns
-  ✓CAIRO_FORMAT_RGB16_565 should be deprecated
-  ✓8379 infinite loop when stroking (see 8379 branch in cworth tree)
+ • Debug environment variable to disable PDF compression (adrianj)
+	http://lists.freedesktop.org/archives/cairo/2007-February/009492.html
 
 For other ideas that have been proposed for cairo but are not yet
 scheduled on the roadmap of any particular release, please see the
 TODO file next to this ROADMAP file.

+Targets
+=======
+Firefox 3.0 - http://www.mozilla.org/projects/firefox/roadmap.html
+------------------------------------------------------------------
+Firefox 3 is the first release expected to use cairo for all
+rendering. In the meantime, development builds using cairo are
+available. Late June 2007 appears to be a rough deadline for when
+mozilla would like to freeze on a cairo release, (as mentioned by
+Vladimir in a cairo meeting on 2007-04-02). No new cairo API is
+needed, but performance improvements are always appreciated.
+
+GNOME - http://live.gnome.org/TwoPointSeventeen
+-----------------------------------------------
+GNOME has a regular (6 month) release schedule, so there's always
+another GNOME release coming up soon.
