Hi.

I've decided my app is gonna have to use 256 colour images and there will be
quite a few of them blitted about, some of which using operations not
available through the OS so I need to make my own blitting routines. I have
a few questions if I may.

1)    Is there a way to force a device to using 256 colours, or fail in the
attempt if it can't manage it ?  I'm thinking more about newer machines
which *may* have 16 bit colour support. Can I then reliably make an
offscreen window that will server as my canvas that I can fill up then copy
to the viewing screen in one go when finished ?

2)    I won't be using *any* of the OS gui functions so I'm assuming I can
nuke the entire palette with my custom colours as long as I put em back when
my app quits. Is this doable ?

3)    Is their a definitive reference on this subject ? I saw one once a
long time ago, but since coming back into the palm world I can't find
anything that covers the specific topics I'm looking for

Many thanks in advance...
