Test whether the given format and usage flag combination is
allocatable.
If this function returns true, it means that a buffer with the given
description can be allocated on this implementation, unless resource
exhaustion occurs. If this function returns false, it means that the
allocation of the given description will never succeed.
The return value of this function may depend on all fields in the
description, except stride, which is always ignored. For example,
some implementations have implementation-defined limits on texture
size and layer count.
\return 1 if the format and usage flag combination is allocatable,
0 otherwise.
