*
* We're doing this...
*
* instead of boxing the texture :
* |<-texture width ->| -->pow2width| /\
* |111111111111111111| | |
* |222 Texture 222222| boxed empty | texture height

* |444444444444444444| | \/
* ----------------------------------- |
* | boxed empty | boxed empty | pow2height
* | | | \/
* -----------------------------------
*
*
* we're repacking the data to the expected texture width
*
* |<-texture width ->| -->pow2width| /\
* |111111111111111111222222222222222| |
* |222333333333333333333444444444444| texture height
* |444444 | |
* | | \/
* | | |
* | empty | pow2height
* | | \/
* -----------------------------------
*
* == is the same as
*
* |<-texture width ->| /\
* |111111111111111111|
* |222222222222222222|texture height
* |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
* rendering. If an app does, the SFLAG_DYNLOCK flag will kick in and the memory copy won't be released,
* and doesn't have to be re-read.
