No.  But thanks.  :-)
I am sending a REDRAW_THE_CANVAS message right now.  I don't like that.
See, in Windows, when I write a bunch of characters to the canvas, it
doesn't redraw after each character, or if it does, it stops the redraw once
you write to it again because it's fast.

Under Linux, I am telling it to redraw when I'm done sending all the text.
There must be a method in Windows for controlling this, like only draw the
canvas (if needed) every 500 ms or something.  If I write 200 characters to
the canvas, I don't want it to actually update the screen until
1) I'm done drawing
or
2) There is a pause in the drawing..
