-
- The point on cacheing covered windows for fast updates is good!
-
- I've always thought that the window manager (or someone in the ROM) ought to
- keep copies of things getting obscured (but mark the blocks of memory as
- purgeable) and if it is still available upon an update event then the manager
- automatically does the update and the application never receives the event.
-
- There may be a need to add a new procedure like SetForceUpdate(TRUE/FALSE) or
- something since some applications, upon changing the data shown in a window,
- simply invalidate it to have the window contents updated.
-
- Perhaps cacheing should be looked at at the ROM level, but for now it would be
- great if MacApp handled that... talk about major speed improvements!
