thanks nick!
1. overlaying the map on other content. for iOS, wouldn't this work:
view.opaque = NO;
view.backgroundColor = [UIColor clearColor];
and then in the gl render code:
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
2. not really needed, just asking
3. cool, thanks. is this available in beta1 right now?
when is beta2 going to be released?
