Details

To reproduce this, load a page (I used http://uk.imdb.com) in seamonkey while
your display is set to 16-bit color. When it's finished, switch the color depth
to 8-bit using the control strip (or whatever). The page background goes black
(from white). 24-Jan-99 build.
Setting all current Open/Normal to M4.

Looks like when switching between absolute and indexed color there's some
confusion over the black and white palette entries (they're typically at opposite
ends of the palette between Mac and Win32 and we're only seeing the problem on
the Mac)

This needs to have the depthChanged event supported.
Look at the window implementation.. this should delete the offscreen buffer and
create a new buffer and deviceContext at the correct depth.  Then re-layout into
this new buffer.  If you need any help at the graphics level just let me know..
currently to get things working.. that event needs to be supported in the view.
