[OpenMap Users] OMScalingRaster setRotationAngle() question

Don,
 
I am using an OMScalingRaster object to display thumbnails of satellite
imagery on the map. It works great for imagery that's not rotated but
when I use the setRotationAngle() method of the OMScalingRaster class,
the image rotates correctly, but the image moves out of the correct
location as I zoom out on the map, in other words it moves to the right
the more I zoom out. Do you know why this is happening? Could it be
that the translation matrix is being applied to the transform after the
rotation matrix in the OMRasterObject render() method?
