-
- • 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

- This is work to be done in the cairo-analysis-surface layer
- and will benefit ps, pdf, svg, and any other
- analysis-surface-using backends.
- Adrian has started work on this:
- http://lists.freedesktop.org/archives/cairo/2007-June/010774.html
-
- • David Turner's cairo-ft rewrite. (behdad)
- http://david.freetype.org/cairo/

-
- ✓ New cairo-xlib API to support IncludeInferior Pictures (see bug
- 10329 for one proposal.
-
- • New cairo-xlib-xrender API:
-
- XRenderPictFormat *
- cairo_xlib_surface_get_xrender_format (cairo_surface_t *surface);
-
- • Make cairo-quartz a supported backend (vlad)
-
- • Make cairo-xcb a supported backend (Jamey Sharp)

-
- • API to allow enable/disabling certain subsetters (adrianj)

- This would also be useful feature to control via an environment
- variable as it would allow the user to override the application

-
- • Debug environment variable to disable PDF compression (adrianj)
- http://lists.freedesktop.org/archives/cairo/2007-February/009492.html
-
-cairo 1.8
-================================================================
- • API to set surface metadata (title, author, etc). This should be a generic
- surface API.

- http://lists.cairographics.org/archives/cairo/2007-September/011441.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.
-
-Where does the information on this roadmap come from?
-=====================================================
-The intent is for this to be a living document. We want both the users
-of cairo, (GTK+, GNOME, Mozilla, Mono, etc. etc.) to let us know
-features they need and dates by which they are needed so that we can
-use those to guide our plans.
-
-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.
-
-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.

-This file contains a list of some things that have been proposed for
-inclusion in cairo. None of these items have been scheduled for a
-particular release, (see the ROADMAP file next to this TODO file for
-those).
-
-If you'd like to see an item on this list get into a particular
-release, let us know that you're planning on working on it, (see
-http://cairographics.org/lists ), and we can move the item to ROADMAP
-with your name on it.
-
-Changes that add new API (API changes/removals will not be considered)
-======================================================================
- • Add CAIRO_FILL_RULE_INVERSE_WINDING and CAIRO_FILL_RULE_INVERSE_EVEN_ODD
- or another way to provide that functionality.
-
- • Add support for programmatic patterns, (ie. arbitrary gradients)
-
- • Add cairo_arc_to.
- see http://lists.freedesktop.org/archives/cairo/2005-August/004801.html
- or see arc_to branch in bedhad's repository
-
- • Add 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.
-
- • Polling API (cairo_get_serial and cairo_changed)
-
- • cairo_save/restore_path()
- http://lists.freedesktop.org/archives/cairo/2007-April/010363.html
-
- • cairo_copy_clip() and cairo_copy_clip_flat()
- http://lists.freedesktop.org/archives/cairo/2007-April/010520.html
-
-Performance improvements
-========================
- • Add dashing support to the fast-path rectilinear stroking
- code, (will help GTK+ focus rectangle, for example)
-
- • Improve software polygon compositing by doing it in a
- single scanline pass rather than tessellating, rasterizing, then
- compositing the entire polygon.
-
- • Clip trapezoids that are partially outside the clip region
-
-Other fixes
-===========
- • Fix/define tolerance for PS/PDF/SVG backends
-
- • Fix CAIRO_EXTEND_REFLECT in pixman and remove the current hack
-
- • Fix disabled show-glyphs-many case in cairo test suite
-
- • Get pixman merged up with X server fb implementation
-
- • Possibly remove pdiff (slows down the test suite with little
- benefit)
-
- • Make font backends separable from their native surfaces
-
- • Fix cairo so that a degenerate matrix draws nothing rather than
- triggering an error state. That is: cairo_scale (cr, 0, 0); should
- not cause an error, (though maybe it shouldn't actually draw
- _nothing_ for painting an infinite source pattern---compute the
- average color for a surface-based source pattern perhaps?).
-
- • The new tessellator has greatly improved performance, robustness,
- and code readability, but may still suffer from "missed
- intersections" as described here:
-
- http://cm.bell-labs.com/cm/cs/doc/93/2-27.ps.gz
-
- [Hobby93c] John D. Hobby, Practical Segment Intersection with
- Finite Precision Output, Computation Geometry Theory and
- Applications, 13(4), 1999.
-
- We could do multi-pass Bentley-Ottmann or add a tolerance-square
- pass as described by Hobby in the paper above.
-
- • Fix vertical metric and TrueType subsetting:
- Text drawn with vertical metrics cannot currently use TrueType
- subsetting for PDF/PS output as the code doesn't write out the
- necessary VHEA or VMTX entries to the TrueType font
- objects. As a result, cairo uses Type3 fonts which generates
- slightly different outlines. Type1 has the same problem.
-
- • Pen matrix locking. Carl has written an excellent summary but
- unfortunately that was not sent to the mailing list. Ask him.
-
- • Explore Render-like component-alpha ARGB masks
-
-Backend-specific improvements
-==============================
- Win32 backend
- • Fix self-copy test
- • Fix trap-clip test
-
- PS/PDF improvements
- • Fix extend modes in PDF
- • Use glyph advances to generate more compact PostScript (done for PDF)
-
- Xlib backend
- • xlib backend requires xrender to compile, while it can perform without
- xrender at run time. Make it compile without it. see
- http://lists.freedesktop.org/archives/cairo/2006-October/008075.html
- • Switch to server-side gradients
- • Switch to using XRenderAddTraps rather than XRenderCompositeTrapezoids
- • Use XlibRectStretch for nearest-neighbor image scaling.
