- * 1) Fill (mandatory, solid color/gradient/pattern/image draw)
- * 2) Image composition (image mode multiply and stencil)
- * 3) Mask
- * 4) Extended blend (multiply/screen/darken/lighten)
- * 5) Premultiply/Unpremultiply
- * 6) Color transform (to black and white)
+ * 1) Paint generation (color/gradient/pattern)
