Billy Biggs	33599bc6b6	Fix for bug #4172: ... Use _cairo_fixed_to_double and _cairo_double_to_fixed when converting between double and 16.16 fixed point. These functions round nicely, and solve some inconsistencies in rendering between my PPC and x86 machines. Thanks to Owen Taylor for suggesting the fix. The above change does affect linear gradients slightly, but it seems worth it. Update the reference images to follow.	2005-08-21 14:10:39 +00:00
Carl Worth	c0d9c13d04	Make gradient change color in addition to just changing alpha in order to highlight distinction between interpolating in premultiplied vs. non-premultiplied space.	2005-04-14 14:02:03 +00:00
Carl Worth	d1eb620a19	Add gradient-alpha test in preparation for upcoming cairo_set_source patch.	2005-04-14 09:31:21 +00:00
