54             draw this image using any kind of graphics api you want.
55             in the technical sense we allocate some space in local
56             videomemory or AGP memory which will be filled on demand,
57             which means if there exists any rendering operation that
58             needs to read from this memory location.  this method
59             creates a logical hardware surface object which uses the
60             given color buffer as the image source.  internally this
61             texture may be distributed to several real hardware
62             surfaces.
