This adds support for the fn key on macOS. It adds it to the key mappings as a supplemental mapping that overwrites the one from the Chrome headers, since the chrome headers have a TODO, but no implementation of the key. Also, ignore the fn key entirely on macOS. This is because On macOS laptop keyboards, the fn key is used to generate home/end and f1-f12, but it ALSO generates a separate down/up event for the fn key itself. Other platforms hide the fn key, and just produce the key that it is combined with, so to keep it possible to write cross platform code that looks at which keys are pressed, the fn key is ignored.

// These are supplemental key codes to be added to those that Chromium
|
|
// defines. Since the web doesn't have game controller buttons defined in the
|
|
// same way, these map USB HID codes for game controller buttons to
|
|
// Android/Linux button names.
|
|
//
|
|
// The HID codes here are not real USB HID codes, because the USB HID standard
|
|
// doesn't define game controller buttons in this way. It defines only two
|
|
// button "collections" (fire/jump and trigger), with the button number for
|
|
// each collection sent as extra data. Since we're just using USB HID as a
|
|
// convenient namespace, and not using these HID codes for interfacing with a
|
|
// USB protocol, we can define new ones to enumerate the buttons. These don't
|
|
// collide with any currently defined HID codes.
