373=head2 GLX SUPPORT
374
375Due to the sad state that OpenGL support is in in Perl (mostly the OpenGL
376module, which has little to no documentation and has little to no support
377for glX), this module, as a special extension, treats context creation
378properties C<OpenCL::GLX_DISPLAY_KHR> and C<OpenCL::GL_CONTEXT_KHR>
379specially: If either or both of these are C<undef>, then the OpenCL
380module tries to dynamically resolve C<glXGetCurrentDisplay> and
381C<glXGetCurrentContext>, call these functions and use their return values
382instead.
383
384For this to work, the OpenGL library must be loaded, a GLX context must
385have been created and be made current, and C<dlsym> must be available and
386capable of finding the function via C<RTLD_DEFAULT>.
