As a programmer new to X and X Toolkit, I have a question.  I am
using X11R3.

What is the accepted way to render graphics into a widget?  Should I
create my own widget to handle the graphics or can I grab the window
of a generic Core widget, and render into the window?

I have an application that uses 20x18 bitmaps, from 400 to 4000 of them.  So,
I assume I need to use XCopyPlane or XCopyArea.  Any hints will be greatly 
appreciated.  I want the result to be managed by a Viewport widget.

Another question.  How do I determine if a machine is monochrome or color?
I thought I could determine it by examining the depth of an open screen.  But
it always returns 8, even on a monochrome machine.  What am I missing?

Any help will be greatly appreciated!!
