Yes. But note that the first sentence only applies to the UNIX
platforms (painting isn't supported in the Win32 engine, yet).

There's no fixed boundary here, though remapping 24-bit color images
down to 8-bit is no walk in the park. What format were these images?
If not JPEG, you should strongly consider either using that format or
drastically reducing the number of colors you're using (e.g. remap all
the images to a standard colormap with fewer than 200 colors).
Otherwise, your stacks will be much larger (and much slower) than they
need to be.

The "color hog" problem only applies to 8-bit color modes.

Right. The privateColors property only applies to systems running in
8-bit (256 color) mode. In the 16 and 32-bit color modes, the
colormap is fixed.

Please send bug reports to support@metacard.com. Include details on
your platform (like what kind of video card you're using), and any
stacks or images you're using if the problem only occurs with
particular stacks or images. A recipe that includes *exactly* what
you have to do to reproduce the problem is also greatly appreciated.
