JAI - change minX and minY on image after scaling

I am trying to create a mosaic (using the MosaicDescriptor) from a bunch of images that I have scaled to make smaller. As an aside I am scaling the images first so that I can make them all the same size before creating a mosaic, rather than create the mosaic and then scale.

The problem that I am running into is that the ScaleDescriptor ignores the ImageLayout rendering hint, which is where I would like to set the minX and minY.

I have four images that given the proper x/y will create one image with the mosaic descriptor
image1 = (0,0) x/y
image2 = (1, 0) x/y
image3 = (0,1) x/y
image4 = (1,1) x/y

Scaling seems to always leave the image in the 0,0 position so my four images all sit on top of each other.

Is there a way that I can get the ScaleDescriptor to set the minX minY correctly? Or is there another descriptor that I should call to set the minX and minY?
