 *   Before using a texture format, it is recommended that the corresponding
 *   bit be checked.
 * @paddings: Padding bytes.
 * @gpu_available_memory_size: Theoretical maximum memory available to the GPU.
 *   It is unlikely that a client will be able to allocate all of this memory
 *   for their own purposes, but this at least provides an upper bound on the
 *   memory available to the GPU.
 *   This is required for OpenCL's clGetDeviceInfo() call when
 *   CL_DEVICE_GLOBAL_MEM_SIZE is requested, for OpenCL GPU devices. The
 *   client will not be expecting to allocate anywhere near this value.
