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