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
Billy Biggs	17845df95b	Fix for bug #4165: ... Use pointer comparison for coincident points to ensure a well-defined ordering, and avoid setting discard on both points. This fixes problems with my Mac's implementation of qsort. Final patch by Bertram Felgenhauer. Update reference images after the change.	2005-08-21 11:41:44 +00:00
Owen Taylor	e7607bb379	Comment and clean up the gradient computation. (_cairo_linear_pattern_classify): Determine if a linear gradient is horizontal or vertical. (_cairo_pattern_acquire_surface_for_gradient): Optimize horizontal/vertical gradients with a repeating surface. ... Test case for linear gradients at angles and with a rotated pattern matrix.	2005-03-06 12:05:23 +00:00
