shadowImage() Coordinates Have no Effect

[jmorfis]

->shadowImage() seems broken.

The x, y coordinates do not have any affect. The shadow coordinates appear to be fixed slightly to the bottom-right as you increase the sigma. But the x,y (parameters 3,4) do nothing.

These two yield the same exact results: $shadow->shadowImage( 100, 2, 0, 0 ); $shadow->shadowImage( 100, 2, 100, 100);

After some testing it seems like the offset is actually based on the $sigma param. To position the shadow behind the original I have to offset it - 2 * $sigma.
