- In shortly, it is all what OpenGL has. When destroying a context that means OpenGL will be destroyed as well.
- More specifically, OpenGL context is a super large state machine that holds every data related to the rendering of our application. And OpenGL context is a thread-local variable and that means in a process there are many threads or current OpenGL contexts, each one can only have access to its own data. Basically, it is isolated to eachother, hence a context cant change any other contexts.
