[XForms] OpenGL and Threads- again

[Nicolas Castagné]

	This mail is addressed to those that use OpenGL within XForms.

	I have had no answer concerning my last message, but I really think 
the subject of threads and openGL is of interest for the XForms 
community.....
	My aim concerning this question is to add a small demo to the XForms 
demo programs.

	So, let's play again !

-------

	You will find enclosed a short program which implements a GLCanvas 
drawn by a thread.

	This program is stable with direct rendering. However, it is not 
stable on my IRIX system in case of rendering through the X sever, 
especially in case of a distant execution.

	-> Could some of you try to compile this program and run it locally 
and on a distant machine ? 10 min. work !

-------

	The next part of the message is addressed to those who have 
successfully implemented a GLCanvas drawn by a thread.

	Did you tried non-direct rendering on these canvas ?
	If it runs properly, it would be very helpful if you could have a look 
to my code and give advices !


	Thx ,

	Nicolas
