Depth buffer option

[James W. W. <ja...@wr...>]

I'd like to add an option to Quesa to leave the depth buffer 
uncleared when rendering.  I'm wondering what sort of API to use. 
One option would be to add a flag to the 
TQ3DrawContextClearImageMethod enumeration.  However, the option may 
not make sense for non-OpenGL renderers.  Another option would be to 
do it like the depth buffer depth, with a custom element attached to 
the renderer, view, or draw context.
