It doesn't need to be smaller or have a different alignment. Creating
two resources with the same properties at the same heap offset should
work. If these share the same heap allocation, modifications to one
should be visible in the other (after the appropriate barriers, etc.),
if they get separate allocations modifications wouldn't be visible.
