We are trying to improve the graphical (bitmap rendering) performance for
the BeOS port. One issue we face  lies in our current display model: squeak
renders into its own bitmap, then we translate the squeak bitmap image into
a BBitmap with the same pixel configuration as the display, then
invalidated screen areas are drawn out of the BBitmap backing store. What
is done on other platforms? Is the Squeak UI the same on all platforms?
I.e., on any of the supported platforms, does squeak use "native" windows
for its windows, or do all platforms render into a window like is currently
done on the BeOS?

thanks,
