the rules used to determine the shading of components
does not work correctly on solaris. there are several areas
of concern:
1. by default an editable text field
has a white background. when you
change the color of the textfield,
its background changes to the background
color not a lighter version. The background
of an editable textfield should be lighter.
2. if i change the background color of
a scrollbar dynamically, the trough
changes to black, rather than a darker
shade of the background color.
sometimes when you bring up a new
window, the trough is the same as the
background. this is incorrect.
3. push & check buttons. in some cases
there is no shading. these colors
are able to be shaded, but instead
a black borser completely surrounds
the component. this happens on
other components as well.

I have included some code demonstrates the problesms.
it allows you to cycle through 6 colors to see. the
different effects.
