Syntax for image-pattern support in CSS

I hope so, cause I don't want to do that much work for the tweak! :-)

That is a really good question. It seems to me that it must be shape origin. I will write some tests to see if I got this right. As I read the ImagePattern documentation, it seems that this is what (0, 0) means -- relative to the shape's upper left corner (not the origin)?

 * <p>The {@code ImagePattern} class fills a shape with an image pattern. The
 * user may specify the anchor rectangle, which defines the position,
 * width, and height of the image relative to the upper left corner of the
 * shape. If the shape extends out of the anchor rectangle, the image is tiled.
