-/** Encapsulates the workaround of running all display operations on
- the AWT event queue thread for the purposes of working around
- problems seen primarily on ATI cards when rendering into a surface
- that is simultaneously being resized by the event queue thread.
- <p>
-
- As of JOGL 1.1 b10, this property defaults to true. Problems have
- been seen on Windows, Linux and Mac OS X platforms that are solved
- by switching all OpenGL work to a single thread, which this
- workaround provides. The forthcoming JSR-231 work will rethink how
- such a mechanism is implemented, but the core result of needing to
- perform all OpenGL work on a single thread for best compatibility
- will remain.
