You can't use the render target size here. You have to use the texture size of
the texture you're sampling from. In all your apps the texture happens to have
the size size as the render target, but that isn't necessarily the case.

You can get the texture sizes from
device->stateblock->texture[i]->currentDesc.(With,Height). You have to keep in
mind though that the texture doesn't have to be a 2D texture(the shader code is
checking that already, otherwise it won't generate a RECT read), or it could be
NULL.
