This is a known annoyance.  I don't know if this is done on all platforms
or just Windows; it's not documented, AFAIK.

I've offered to fix this, and Sam seemed to want a fix, but he hasn't
responded to my questions of exactly how this should be fixed.  Windows
*must* reset the OpenGL context when some settings are changed, so we need
an interface to indicate whether the context is reset; I need to know
what type of interface will be accepted.  (This is one of my more major
patches that I'm maintaining a fork for, and as I hate maintaining
forks, I'd very much like to get this cleaned up and put into CVS.)

Sam, I understand that you're busy; could you at least give an indication
that you havn't forgotton about this?  :)

(I hadn't thought of doing this via a message.  Sam, would sending a
message indicating that the OpenGL context has been reset be a reasonable
way to do this that you'd consider applying to CVS?  I like it because it
doesn't add an entry point, just a message type, and it gives a way to
handle the theoretical future case where the OpenGL context is lost for
other reasons.)
