		375	Due to the sad state that OpenGL support is in in Perl (mostly the OpenGL

		379	specially: If either or both of these are C<undef>, then the OpenCL
		380	module tries to dynamically resolve C<glXGetCurrentDisplay> and
		381	C<glXGetCurrentContext>, call these functions and use their return values
		382	instead.
		383
		384	For this to work, the OpenGL library must be loaded, a GLX context must
