++** software buffers and things which are associated with the drawable,
++** and used by any context which draws to that drawable.  There are

++** since drawables and contexts can be created and destroyed independently
++** of one another, and the "operating system" may want to use separate

++** The freePrivate function is filled in by the core routines when they
++** allocates software buffers, and stick them in "private".  The freePrivate
++** function will destroy anything allocated to this drawable (to be called
