//Information on the current memory resources available can be queried
//by specifying VBO_FREE_MEMORY_ATI, , or
//RENDERBUFFER_FREE_MEMORY_ATI as the value parameter to GetIntergerv.
//These return the memory status for pools of memory used for vertex
//buffer objects, textures, and render buffers respectively.The
//memory status is not meant to be an exact measurement of the system's
//current status(though it may be in some implementations), but it is
//instead meant to represent the present load such that an application
//can make decisions on how aggressive it can be on the allocation of
//resources without overloading the system.The query returns a 4 - tuple
//integer where the values are in Kbyte and have the following meanings :
//
//param[0] - total memory free in the pool
//param[1] - largest available free block in the pool
//param[2] - total auxiliary memory free
//param[3] - largest auxiliary free block
