Expand description

A trait for types that can be used as a context for OpenGL, OpenGL ES, and WebGL functions.

This trait is sealed and cannot be implemented outside of this crate.

§Safety

All GL API usage must be valid. For example, each function call should follow the rules in the relevant GL specification for the type of context being used. This crate doesn’t enforce these rules, so it is up to the caller to ensure they’re followed.

The context implementing this trait must be current when it is dropped. This is necessary to ensure that certain context state can be deleted on the correct thread. Usually this is only a concern for desktop GL contexts that are shared between threads.
