From the spec:
"IMAGE_FORMAT_COMPATIBILITY_TYPE: The matching criteria use for the
resource when used as an image textures is returned in
<params>. This is equivalent to calling GetTexParameter"
So we would need to return None for any target not supported by
GetTexParameter. By mistake, we were using the target check for
GetTexLevelParameter.
