I think that's an interesting idea. The way it works currently, all these
functions are also exported so there isn't another GL library. If we were to add
context argument here, it would mean that we do need an actual GL library that
puts the current context in TLS and so forth. I like that, it removes the
complexity from our proxy layer. We could also #define all those functions. We
should talk about this today.

Yes removing complexity is the goal. TLS should be part of the helper library.
We could either create two helper libraries - gles and egl, or fold them into
one pgl library. I am not a big fan of #define because I ran into nasty issues
while porting OpenSceneGraph.

     for func in self.original_functions:
-      if func.GetInfo('extension'):
+      if func.GetInfo('extension') or func.name == 'SwapBuffers':
         continue
       file.Write("  %s (*%s)(%s);\n" %
                  (func.return_type, func.name,
