Try sending "asFormOfDepth: 32" to your form, and you'll get back a
32-bit form that allows you to use any colors you like.

As far as I know, operating on forms with colorAt: and colorAt:put: is
the simplest way to get going.  For speed, you will probably want to
hook into BitBlt eventually.  BitBlit isn't as limitting as it might
sound -- for example, it has an operation to mix rectangular regions of
two forms into another form, using alpha to mix.  Thus, for example, you
should be able to get a blur effect by mixing an image with itself at
various 1-pixel offsets.  You can do a Sierpienski triangle by turning
on a pixel at the top left corner, and then XOR-ing each row of a form
with that same row at a 1-pixel offset, and then copying the result to
the next row.
