OpenTK 4.5.0 Upgrade

[optimus-code]

Hi

I just thought it would be useful to list some breaking changes I have so far discovered trying to upgrade to OpenTK 4.5.0.

Breaking changes

• AudioContext and accommodating higher level audio classes are no longer part of OpenTK.
• Underlying window system changed, no longer based on System.Windows.Forms and you need to use the low level GLFW apis.
• Input routines changed as a result of the new windowing system.
• Video mode selection is now done with low level GLFW api.

I'll add more points when/if I discover them.

I see, I just updated it and it broke the project. 😂
