hey,
...I've put up a binary of the multiple_window test version for OSX on my homepage:
http://homepage.mac.com/tigital
...this is compiled for G4's, so don't run it on a G3...included is an example patch, showing how the stuff works: if you don't send an offset message, by default the windows will be created on top of each other...to move them, cmd-click on the the windows title bar: this won't bring the window to the foreground in the finder (for reasons that are detailed elsewhere), but will allow you to move it around, even to another screen...I've only tested it on two powerbooks, so I'm looking for feedback on how it works with a computer with multiple display cards...
...also note that [gemwin] has been changed into an abstraction (included) to keep backwards compatibility...
l8r, jamie
ps; the multiple_window tag was branched about 6 months ago, so don't expect all of the fixes/changes since then, especially the vertex_array stuff...
