Graphics window modes

The doc states...
"Improved support for windowed modes will be added shortly"
Has this happened yet (and I missed it) and, if not, any ideas when it will be available?

Perhaps it relates to the GUI module...

Not really.
It related to the graphics 640,480,depth,hertz command.
Currently there's fullscreen or depth=0 for windowed. The manual states depth=0 is for debugging only.
You can use undocumented -1 for an odd window/no title bar mode.

Guess we'll have to wait and see...
