		366	=head2 GLX SUPPORT
		367
		368	Due to the sad state that OpenGL support is in in Perl (mostly the OpenGL
		369	module, which has little to no documentation and has little to no support
		370	for glX), this module, as a special extension, treats context creation
		371	properties C<OpenCL::GLX_DISPLAY_KHR> and C<OpenCL::GL_CONTEXT_KHR>
		372	specially: If either or both of these are C<undef>, then the OpenCL
		373	module tries to dynamically resolve C<glXGetCurrentDisplay> and
		374	C<glXGetCurrentContext>, call these functions and use their return values
		375	instead.
		376
		377	For this to work, the OpenGL library must be loaded, a GLX context must
		378	have been created and be made current, and C<dlsym> must be available and
		379	capable of finding the function via C<RTLD_DEFAULT>.
