teaching platform for the graphics API = OpenGL
An object in OpenGL is a collection of options that represents a subset of OpenGL's state.
id로 저장 -> id를 이용, obj를 target location of the context에 bind -> window option 설정, un bind the object by setting the current object id of the window target to 0
The options we set are stored in the object referenced by objectId and restored as soon as we bind the object back to GL_WINDOW_TARGET
