+ (pixman_image_create_linear_gradient),
+ (pixman_image_create_radial_gradient):
+ * src/icimage.h:
+
+ Some major performance improvements to the general composite code
+ used for gradients and transformed images. Like fetching of mask
+ scanline before source scanline so that only the necessary pixels
+ from source needs to be computed in case of gradients or
+ transformed images as source. This patch also include some
+ gradient specific fixes and performance improvement.
