		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

		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
