I think one of the major questions I'd have with respect to what API
approach to choose is if you want to be able to enable/disable this
without permanently affecting the contents of the bitmap itself, i.e.
do you want the filtering to happen at draw time, or should the actual
bits themselves be affected in the bitmap's storage. If you want on
the fly then I'd say probably the extra method to change the render
mode would be the way to go myself.
