FR: Wrangle a comprehensive set of OpenGL functions & macros

General JUCE discussion
5

Thanks for this FR. I’ve had a go at implementing this here:

Note that is this currently not on develop. Given the scope of this change, it felt safer to put it on a feature branch so that it can get a bit of testing before merging it into develop. You can try out this change by checking out generated-opengl-headers.

I’d really appreciate any feedback you can give about this change, as we don’t have a lot of OpenGL-dependent code to test with here.

Things that have changed:

  • All GL symbols are in juce::gl. You can either manually prefix all symbols, or you can use using namespace juce::gl to make all GL symbols visible in a specific scope. We recommend doing this at the smallest viable scope, so definitely avoid adding this to headers.
  • The JUCE_OPENGL3 preprocessor definition no longer does anything.
