Added additional documentation to the OpenGL example. #141

Closed zedseven closed 3 years ago

zedseven commented 3 years ago

I've gotten the crate working now, but I burned a significant amount of time because I missed the use of VertexAttribDivisor in the example.

I also found the example a little hard to follow as someone who's not super familiar with OpenGL and text processing in general, so the verbosity of a lot of the raw stuff made it hard to understand at first.

This PR isn't anything crazy, but it adds notes here and there to hopefully make it a little easier to understand and specifically marks the VertexAttribDivisor call as important. (the rest of the VAO initialization is more or less what I'm used to, so I missed the one unique line)

Thank you for all your work on this series of crates!

Nice one, thanks!

Burning time getting opengl to behave is also my general experience of that API tbf 😆
