Re: PenguinPlay and 3d

Sorry for putting this on the main list,  I am having a little bit
of trouble with the graphics mailinglist (I have a sneaking suspicion
that I am not subscribed!)

The big thing  I want to see is a _discussion_ about 3d, before we
committo anyting specific.  So far all we know about our goals are this:
    *   OpenGL will be the base of the graphics system.
    *   We will have an OO layer above it.   (We have no idea what that
layer will be like).
    *   We _might_ have a thin low level thing to use instead of OpenGL in
the software only case,
          maybe a gind of mini-Mesa, maybe something completely
different.  This does not make
          sense if software  only Mesa is quick enough.    I am not up to
date enough with Mesa to know
          how well it is going to be optimized.
