[Kst] What do view objects really need?

As far as the pixmap goes, what do view objects really need?  I just committed 
a change that makes them 16bpp, and I was even considering going as low as 
8bpp.  Does this make sense?  Are we even making use of this much colour 
space in each individual view object?  I think we can survive with 8bpp in 
most cases, especially once labels are turned into proper view objects.  Then 
I would consider making the depth of the buffer a parameter to the backbuffer 
class (labels will want something more than 8bpp to have cleaner antialiasing 
I think).

Also, Barth, does the MemoryOptim make a difference for you on the machine 
that experiences pixmap pressure?  Trying to reduce the pixmaps was the best 
that Jim Gettys could come up with when we talked about it for a few minutes.  
He doesn't think hoping for client side rendering to help is very realistic 
(or ideal).  If MemoryOptim doesn't help, I'd like to convert it to something 
more buffered.
