* This means when multiple fragments are writing to a pixel you can choose
precisely the one you want to debug, rather than the debugging always
running the approximately last fragment to pass
* For APIs where the shader namespace/bindpoint (which may be arbitrary
like 'the Nth texture resource' can be mapped, at each event, to the
actual API bind point where the object is.
* On D3D11 this is pass-through, on GL this returns the value of each
uniform.
* This also means GL shader reflection structures are properly immutable
and the variance in the uniform values is handled elsewhere.
* In future this might need to be expanded to support more complex binding
methods, where the mapping returns the resource rather than just mapping
to an integer bind ponit.
For now this just acts like a really wide vector with N columns for the
array, but this could be improved in future if a better visualisation is
decided on.
