From what I understand, each image loaded is converted to the next power of two texture (128, 256, 512). But If I have an object with very different proportions between height widt, it is a waste of memory. Would be nice to have an option to share textures or sprites between different object but assigning differents pieces-areas, mapping. So, this way we can optimice memory, for eve animation, where a character deals different sizes of area-pixels. I think it is a need for a texture palette or linker too.
