/** the whole idea is build around the concept that you create
some arbitrary buffer which contains the image data and
tell the texture manager about it. from there on you can
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.
