<pre>So is the atomicImage* behavior different to imageStore? It's not absolutely
clear from GL_ARB_shader_image_load_store specification: "For example, it is
legal to access an image whose internal format is RGBA8 with an image unit
format of R32UI."
Nvidia and AMD doesn't have a difference between:
layout(r32ui) uniform uimage2D surface;
imageAtomicExchange(surface, ..., packUnorm4x8(color))
layout(rgba8) uniform writeonly image2D surface;
imageStore(surface, ..., color)</pre>
