Lifesaver!

Routine 1:

* Given a bitmap - from loadBitmapFromFile
* Copies it to a specified Pixmap control
* Given the position on the Pixmap control
* Given the size of the bitmap on the pixmap control (ie can be
'stretched')

Routine 2:

* Given a pixmap control
* Copies it to the screen
* Given the position on the screen
* Given the size of the pixmap control on the screen (ie can be
'stretched')

If you could do them, or even explain a little more clearly what needs to
be done,
I will be VERY grateful.
