When you do a screen capture, it is capturing the system (AGP) memory
resident portion of video memory. Since many 3d views are handled
exclusively by the video card, there is no system memory representation of
that data. Screen captures do not (usuallly) pull the data directly off the
card, they pull it from the system (AGP) memory resident copy.
