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>.

1301
1302Returns a string for the compiled binary for every device associated with
1303the program, empty strings indicate missing programs, and an empty result
1304means no program binaries are available.
1305
1306These "binaries" are often, in fact, informative low-level assembly
1307sources.
