Graphics2D.drawRenderedImage draws a child Raster at an incorrect position

A test case is enclosed which provides a minimal implementation of the
RenderedImage interface. The image extends from (100, 100) and is 200x200
in size. It has a single tile which has its origin at (0, 0).

The image's getData(Rectangle) method is implemented so that it may either
return a newly created Raster with its origin at (100, 100), or alternatively
return a child of the tile Raster. A simple UI is provided that allows
toggling between to images, one with each setting.

The images are drawn into a Canvas using the Graphics2D.drawRenderedImage
method. The new raster (yellow) image is drawn corrently, with its origin
at (100, 100). However, the child Raster (blue) image is drawn with
an incorrect origin.
