Detailed Description

a big annoyance with NSShadow is that it ignores the current CTM when it is set, meaning that as a drawing is scaled, the shadow stays fixed.

This is a solution. Here, if you call setAbsolute instead of set, the parameters of the shadow are used to set a different shadow that is scaled using the current CTM, so the original shadow appears to remain at the right size as you scale.
