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