Improvements
* Windows now has an `exit_key` property that can be used to change or disable the exit key. This key is `ESCAPE` by default and can be disabled by setting the property to `None`. This is useful for users that don't want the default exit key behavior.
* Log consumed glerrors after context creation as warnings
Bug fixes
* Pyglet mouse coordinates was translated wrong in cases were the framebuffer size is larger that then window. The mouse position
should always use window coordinates.
* VAOs should now properly support 64 bit floats / dvec
* VAOs should be better at detecting/ignoring built in attributes
* `Camera.look_at` had broken input validation when passing in a vector
* Various typos in docstrings
