Well, we already have 1.5 stuff in the tree and if we receive
contributions for 1.5 stuff, we don't say no :-)

I cannot access this link anymore.

This is nice (I think, haven't seen a screenshot yet) and may even be
useful. I think, gradients could be painted using some Java2D functions,
which we have not implemented yet. Also, such a method could be useful
for systems that don't provide Java2D support.

The method would have to be a little more flexible. I see that in the
OceanTheme, the following UI default is defined:
Key: Button.gradient     Value: [0.3, 0.0,
javax.swing.plaf.ColorUIResource[r=221,g=232,b=243],
javax.swing.plaf.ColorUIResource[r=255,g=255,b=255],
javax.swing.plaf.ColorUIResource[r=184,g=207,b=229]]

The gradient method should take such values as parameters. This seems to
be 2 double values (a vector?) and 3 color values. I haven't figured out
the exact meaning of those values yet, but maybe you can make some sense
of it? Would be very helpful, if you could say something to it, or even
can provide some code. Your gradient function already looks promising
and I would be happy to integrate it into
javax.swing.plaf.metal.MetalUtils. For code contributions you should
also ask Mark about the copyright asssignment stuff.

As I said above, the colors should be parameters to the method :-)

Cheers,
Roman
