Hi Denis,
That sounds like some very good ideas for making this method very accurate.
On the other hand, we're starting to get into the territory where an
advanced math package should be catering to these requirements. The
solveCubic was an internal helper function for implementing the hit

Sure, that sounds good. Reading through the code I found, I spotted
a few things that might have been problematic in some extremely
rare cases. I've been working o

This is a forward port of the second half of the fixes in 6u12 for doing
fast transformed rectangles and wide lines. This time the AA pipelines
are upgraded to handle parallelograms directly and some new native loops
are added to do direct rasterization of AA parallelogram filling and
stroking
Hi Pavel,
I think these are 2D tests. I'm copying 2d-dev@, and BCC'ing awt-...@.

Hello.
Please don't review these yet. I'm making some modifications
to make them much more robust. We should have a new version of
the tests in maybe one hour (at most).
