I'm running Snow Leopard, myself.

Alexandre specifically suggested that I suppress the grow box in the Mac driver since drawing resize widgets should be up to the Windows app, so that's what I did. It's the call to [window setShowsResizeIndicator:NO] in cocoa_window.m.
Also, Jörg already was aware that windows may be resized when they don't show grow box, since he noted that there isn't one with the X11 driver. So what he reported is something else.

You can even use an IOSurface as a GL texture (and, by extension, render with OpenGL into the IOSurface). This is how Chrome (and probably Safari too, since it uses the same underlying engine) implements sandbox'd rendering: the renderer draws the page into an IOSurface, then the browser draws the IOSurface into the window. And yes, this will work on Snow Leopard.
I'm aware of IOSurface. It's one of the shared-memory mechanisms I mentioned as being in consideration. As always, patches welcome! ;)

> Why aren't we using Option as Alt? Nearly every Mac keyboard labels it as "Alt" these days. Is typing characters like 'ü' and 'ø' and '∆' really that important? :)
Given the smiley, I can't tell if you're joking or not, but, yes, accessing additional characters from the keyboard layout is important. CodeWeavers' experience with support requests actually strongly influenced my decision to reserve Option for that. I'm open to introducing a registry setting to allow that to be changed.
And, yes, it sucks that the key is labelled Alt but can't be used as Alt. :(
