I am really really interested in a solution that would cause DeskCalc
to resize smoothly but I've yet to find it.
If I take out both the B_FULL_UPDATE_ON_RESIZE and Invalidate() from
FrameResized() then the view doesn't redraw at all.
If I keep the B_FULL_UPDATE_ON_RESIZE flag but don't Invalidate() in
FrameResized() it redraws the view before FrameResized() gets called
so the view gets drawn on resize, but incorrectly.
If I include both B_FULL_UPDATE_ON_RESIZE and Invalidate() in
FrameResized() as it was before it draws the view twice each time the
view is resized, once before FrameResized() and a second time at the
end of FrameResized(). By taking out the B_FULL_UPDATE_ON_RESIZE flag
I've eliminate a superfluous Invalidate() call on resize, but it
doesn't help to make the drawing any smoother. I'm still stuck on how
to do that.
