The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. + The new algorithm produces slightly larger number of splits, which is + compensated by its simplicity.

When inlined into + `gray_render_cubic', this makes the function faster by 10% and is + noticeable in the overall rendering performance. + * src/raster/ftraster.c (Split_Conic, Split_Cubic): Use shifts and refactor. * src/smooth/ftgrays.c (gray_split_conic, gray_split_cubic): Ditto. |
