- Couldn't you bottom a window simply by topping all other windows
- in bottom to top order? The superfluous redraws could then be handled
- by queueing redraw messages for the topped windows until the bottom operation
- was finished, discarding messages for windows that were originally above the
- bottomed window.
- (You would have to do the queueing yourself, reading the message
- pipe after each top operation since the AES message pipe is short.)
-
- Of course this sort of mucking about should be hidden in a library that
- checks if AES supports bottoming directly for efficiency.
