[Bf-committers] sources for 2.23

[Daniel Dunbar]

What is actually happening is that after the ghost change the renderwin
is opened in double buffer mode, which on an older SGI means it is going
to be only a 12bit display, the solution in this case would be to add single
buffer support to ghost. ATM this should work reasonably well, although
really a more refined display/interface level should handle this. (At the
time my plan was to enhance the render window with more imaging features,
and user interface elements to support that - having to worry about testing
with single and double buffers adds undeserved complexity IMHO).

The quick fix solution would be:
Add single buffer mode argument to C++ ghost constructor
Add same arg to GHOST_CreateWindow
Add same arg to window_open
Add code to renderwin.c to determine what mode to use.
