I am trying to write a color paint program.  I would love to know how I can 
make use of TextEdit to implement the text tool in the tool palette (the 'A' 
icon).  Specifically:

	[1] How do I prevent existing graphics that is in the view rect of text
edit record from being erased?

	[2] When the user types <backspace>, how do I erase the last character
and restore the background graphics that was replaced by the character?

	All existing paint programs seem to be able to do this quite well and
I suspect they make use of text edit since they have the blinking text caret
to prompt users to enter text.  Is this true?

Thanks in advance,
