Subject: Changed locking protocol for on-screen surfaces to only use the
JAWT's DrawingSurface locking primitives during the makeCurrent operation.
While in theory the JAWT should be used for locking for the entire duration
of the makeCurrent/release pair, in practice because OpenGL is orthogonal to
the window system this is not really necessary, at least if higher-level
locking primitives are used to make sure the window is not torn down out from
under the library while OpenGL rendering is being performed. The
OpenGL-related work done in GLCanvas.addNotify() and removeNotify() handles
this. These changes enable simultaneous multi-head rendering on X11 systems
with one OpenGL context per thread. Changed GLContext.destroy() to acquire
the context's lock during the destroyImpl operation for correctness in the
new protocol. Changed several Mac OS X native code entry points to not take
an unnecessary NSView* argument. Tested with several demos on all platforms
to stress creation and destruction of multiple kinds of OpenGL contexts.
