Description Matthias Wienand

The Path#getBounds() method should return rectangular bounds that tightly enclose the path. This seems to be working well for many paths, however, when a path contains cubic bezier curve segments, the returned bounds are too big and not tightly enclosing the path.

I added test cases for the Path#getBounds() method. The tests compare manually computed bounds with the bounds returned by Path#getBounds(). The tests are failing for paths with cubic segments.

The bounds computation was based on AWT. I ensured that the bounds are now computed based on the individual path segments, without delegating to AWT. The computed bounds are tightly enclosing the path. The code is published on the master branch, therefore, I resolve this ticket as fixed for 4.0.0 RC4.
