[cp-patches] Geom bugfixes and docs

[Sven de Marothy]

Hi, 
here are some images for documentation I left out before.
(Not attached, You can find them at: http://www.qc.physto.se/~sven/Geom
Should be easy enough to review! :-) )

Also, the Arc2D.intersects() missed a case before. 
Now it should work.

David Gilbert's helpful mauve-tests also pointed out the API's
definition of 'insideness' isn't exactly what I'd implemented.
contains() should return true for the upper-left corner of a rectangle,
but not the bottom-right. (I'd done the reverse)
So this updates Area,CubicCurve2D, QuadCurve2D and GeneralPath to
conform with this definition.

He also caught some bugs in Area. It now passes all his tests.

        (equals): Check for null.
        (rayIntersects): Fix insideness-test

        * java/awt/geom/CubicCurve2D.java:
        Fix insideness-test
        * java/awt/geom/GeneralPath.java:
        Likewise
        * java/awt/geom/QuadCurve2D.java:
