The gradient code in cairo-pattern.c does really funky things with the "filter" setting of the pattern. It uses it to influence how we interpolate between the color stops. For a gradient from 0 to 1 you can get colors looking like: +------- | (NEAREST) | ------+ / / (GOOD, BEST, BILINEAR) / / .-''''' / (GAUSSIAN) / .. This is clearly wrong ... the color values should always be the second image. Filtering is somewhat meaningful for gradients that change very rapidly - imagine zooming out to infinity on a white-black gradient with EXTEND_REPEAT - we should get uniform gray, not white and black aliasing artififacts. But that's subtle, and entirely different from what is implemented currently.
Move bugs against "cvs" version to "0.9.3" so we can remove the "cvs" version.
2005-08-23 Owen Taylor <otaylor@redhat.com> * src/cairo-pattern.c (_cairo_pattern_calc_color_at_pixel): Rip out all the code for doing anything other than linear interpolation between color stops, instead of doing different funky things based on pattern->filter. (#4184)
