glXWaitGL - complete GL execution prior to subsequent X
GL rendering calls made prior to glXWaitGL() are guaranteed
to be executed before X rendering calls made after
glXWaitGL(). Although this same result can be achieved
using glFinish(), glXWaitGL() does not require a round
trip to the server, and it is therefore more efficient in
cases where client and server are on separate machines.
glXWaitGL() is ignored if there is no current GLX context.
glXWaitGL() may or may not flush the X stream.
GLXBadCurrentWindow is generated if the drawable associated
with the current context of the calling thread is a
window, and that window is no longer valid.
