Its just my personal opinion, but I would recommend not implementing it.
Xorg falls back to software anyway for anything more complex than
solid rectangles and blits
and those code-paths will only be triggered for non-antialised
rendering with solid colors.
Implementing it in Pisces would help every backend OpenJDK supports :)
Just checked and I also ignore the STROKE_CONTROL stuff completly in
the cairo based Jules rasterizer.
Curious how that could be mapped to Cairo, do you know any more
in-depth explanation how it works - or examples how it should look
