[vbox-dev] Strange window offset in screen when using shared OpenGL

Hi,

thanks to all the prior help I've successfully managed to hook into the
shared OpenGL service and enable redirection. So I started to do some
testing with a simple OpenGL cube demo, and what puzzled me is that on the
first invocation of H3DORGeometry is got a rectangle with corret size but
left and top corrdinates were 0, although the window itself is not located
in the upper left corner of the screen. As soon as I start to drag the
window around, I start getting H3DORGeometry calls with correct offset.
Could it be that the test application is wrong or is there some magic
involved in retrieving the window offset for the first time?

Best Regards,
Rudolfs Bundulis
