* unless you want to copy the frame buffer in a texture. You may use that texture so that the device memory
* will only be allocated once, and the system memory (needed to create the texture, at least with open gl) will be released after that.
* A texture_mem could have been used, but it doesn't release memory by itself (added : hmm, well it does since 2/2002 ...).
