1e20a2db0f Bail on NULL utf8 string. 
Don't add two consecutive, identical points when decomposing the spline, (which was leading to an infinte loop in the stroke algorithm when it found a slope of (0,0)).

9e793ee5fc Fixed for latest XCB API. XCB headers can co-exist with Xlib headers now, so Cairo may be compiled with both backends in the same library. http://freedesktop.org/Software/XCBCompletedTasks#17_Mar_2004 2004-03-17 09:44:26 +00:00

0e02e71cf5 Add attribution for many people who have made generous contributions to cairo. This list was generated by sifting through the ChangeLog. Please let me know if I have missed anyone. 
Add some historical notes on cairo development, prior to when we began to maintain this NEWS file.
Add pointer to cairographics.org. Fix to use cairo rather than Cairo when not at the beginning of a sentence.
Remove cairo_current_path, cairo_current_path_flat, cairo_text_extents, cairo_glyph_extents, cairo_text_path, and cairo_glyph_path from the TODO list as they have all been implemented now.

122b2d8504 Bump version to 0.1.18. Includes new functions cairo_current_path, cairo_current_path_flat, cairo_surface_get_filter. Support for XCB backend. Fixes for building in cygwin. Adds cairo_surface_get_filter. 
Add new path query functions.
Implement support for cairo_current_path and cairo_current_path_flat. These functions just provide an interface to _cairo_path_interpret and take care of mapping from device space back to user space.
