OpenGL ES Registry Missing #205

Closed RobertBColton closed 5 years ago

RobertBColton commented 5 years ago

I am looking to use libepoxy also for loading OpenGL ES, but I noticed that among your registry entries you guys only have gl.xml which is part of the combined registry. https://www.khronos.org/registry/OpenGL/index_es.php

Now, I am confused about which header to include for using OpenGL ES, where I would have only the extension points for OpenGL ES and not the ones for OpenGL. I would like it to be such that calling OpenGL functions not supported by OpenGL ES would be a compile-time error. What can I do?

Sorry, we don't have an option for that. Applications may call either desktop or ES from the same code (that's part of the point of this library!), and just like with extensions, it's up to you to make sure that you only take code paths that are valid for your particular context.

Understood, thanks, I just wanted clarification!
