Hmm - that'd require rewriting the toolbar quite a bit because to
avoid the
double-flickering in Windows, the toolbar is double-buffered. It is
possible
though, but I'd have to re-write parts of what I've done, so
that'll have to
wait for v1.1. Watch this space.
It is not so bad... take a look at my BufferedCanvas example which is
designed to be a drop-in replacement for Canvas (just change the
Super from Canvas to BufferedCanvas):

However, drop-in replacement will not work quite as well for you
since you already have a buffer image. The key is to make the
Graphics object you perform all of your drawing operations on to
point to either the Canvas.Graphics (support transparency) or to the
Graphics object of your buffer image. Something like:
Dim g As Graphics
If hasAlphaSupport Then
g = Me.Graphics
Else
If (cBuffer Is Nil) Then cBuffer = NewPicture(Me.Width,
Me.Height, 32)
g = cBuffer.Graphics
End If
// drawing code goes here
