On the same note wouldn't it make sense to also add #defines for these
two names? Like STATE_SORTED_BIN and DEPTH_SORTED_BIN?
This whole area could do with a revamp, but we can probably do
something modest to help in the this case. #define's won't cut it
though as this is compile time, and what Terry is after is ability to
define the bin number at runtime.
The runtime setting is actually already fully support, just not via
the convenience functions for OPAQUE and TRANSPARENT_BIN hints.
Perhaps a global variable and methods for setting the value of bin
would be sufficient. Perhaps one could just set the bin number
directly via the prototype in osgUtil.
