I'm not a huge fan of this name; it's not immediately clear to me what it means :-(
Maybe "hlsl-expression-dimensions"?

This doesn't compile with native for ps_2_0 either (see my comment on 5/5). Part of this is because it uses SV_Position, which is kind of my fault too as I've been using that. We should probably find a way to change that to texcoords instead.
With that hacked out of the way, it breaks because of the following error:
Z:\home\hazel\test.hlsl(83,38): error X5608: Compiled shader code uses too many arithmetic instruction slots (83). Max. allowed by the target (ps_2_0) is 64. Consider increasing optimization level to reduce instruction count.
(Increasing optimization level does nothing, of course.)
