This is part of the multiple window Ffenestri support people wailed
for 5 years back, it's part of the EventSensor logic to at least
support
WindowEventMetricChange := 1. " size or position of window changed -
value1-4 are left/top/right/bottom values "
WindowEventClose := 2. " window close icon pressed "
WindowEventIconise := 3. " window iconised or hidden etc "
WindowEventActivated :=4. " window made active - some platforms only
- do not rely upon this "
WindowEventPaint := 5. " window area (in value1-4) needs updating.
Some platforms do not need to send this, do not rely on it in image
I believe MOST VMs now support the WindowEventClose via this logic so
that people can choose to terminate an image by clicking on the close
window button.
I'd consider part of the base kernel since it's VM event related.

Polymorph-Widgets-Themes uses RestSound, otherwise you could remove
all of sound I think, I've done that
for an iphone image. You need to alter the Object>beep logic to invoke
(somehow) the primtiive beep sound, versus
bring up an entire Sound subsystem to beep.
