/** 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.
