* |333333333333333333|
* |444444444444444444| \/
* --------------------
*
* this also means that any references to allocatedMemory should work with the data as if were a
* standard texture with a non-power2 width instead of texture boxed up to be a power2 texture.
*
* internally the texture is still stored in a boxed format so any references to textureName will
* get a boxed texture with width pow2width and not a texture of width currentDesc.Width.
*
* Performance should not be an issue, because applications normally do not lock the surfaces when

* and doesn't have to be re-read.
