No, it isn't reversed, it only appears to be because of different coordinate
systems.  When generating the image the origin and coordiante system of an
image is used.  This means that the upper left is (0,0) and the lower right of
the image generated is function value (1,1).  This is consistent with the way
all image coordinates work.  Now, you are trying to place the image with its
origin (and coordinate system) over a function as a pattern which uses a
different origin (and coordinate system).

This isn't different from moving the box somewhere else and expecting the
image still to match the other function's origin.
