IIMAGE and imageAtomicExchange support.

[zlash]

Would it be possible to add support for IIMAGE for compute? IIMAGE would be the signed int version of UIMAGE (which exists). I'm asking because I don't know how it would be implemented for all backends.
Also, there seems to be no equivalent of OpenGL's imageAtomicExchange. Would it be feasible to add?
Thanks!

atomicFetchAndExchange

I might be wrong but atomicFetchAndExchange works only for buffers. glsl imageAtomicExchange also uses a texcoord parameter that seems to be missing on atomicFetchAndExchange to select the desired texel to work on.
