Opentk/Source/OpenTK/Platform/Windows/WinRawKeyboard.cs
the_fiddler 672a82983a Major updates to keyboard input. The infrastructure (drivers etc) is ready. Windows raw input works (now implementing multiple devices). The examples need updating for the new input methods.
Updated the ExampleLauncher to not process exceptions. Updated the IExample interface to contain the Launch method. Updated examples and the ExampleLauncher according to the IExample interface.
Synced with gl3 branch.
