# mouselocklost event DOM Implementation

# Extend MouseEvent DOM implementation with movementX, movementY

## [[Stack Trace for nsDOMMouseEvent::nsDOMMouseEvent ctor]] (created on mouse move)

## [[Stack Trace for nsDOMMouseEvent::GetScreenX]]

## [[Where to store the state info (e.g., previous position) between mouse events?]]

# The browser must exit the mouse lock state if the user agent, window, or tab loses focus

# The ESC key should exit mouse lock

# Mouse lock should only work when in Full Screen Mode

# [[Refactor nsIDOMNavigator changes for pointer attribute to be in separate interface]]

# Do we need to add a user pref to enable/disable mouse lock?

# Do we need to do conditional compilation for mouse lock?

# When mouse lock is enabled clientX, clientY, screenX, and screenY must hold constant values as if the mouse did not move at all once mouse lock was entered.

# Freeze mouse pointer in centre of window when mouse lock is enabled (e.g., moving the mouse causes an event, but forces the mouse to go back to the original position).

# Proper IDL documentation for navigator.pointer (see example in https://mxr.mozilla.org/mozilla-central/source/dom/interfaces/html/nsIDOMHTMLElement.idl#103), MouseLockable and its methods, MouseLockLost event, etc.

# Write a JavaScript library to somehow combine element.mozRequestFullScreen() and navigator.pointer.lock(). It would be good to hide the complexities of doing fullscreen then locking in a single API call.

# Convert Rescue Fox to use Mouse Lock, see https://github.com/mozilla/rescuefox

# Convert http://cjcliffe.github.com/CubicVR.js/cubicvr/samples/fps_demo/level1.html to use Mouse Lock

# Tests, tests, tests. We need tests for all aspects of the spec. List tests we need below:

## <test cases go here...>

# Create a tutorial on how to use Mouse Lock, with code examples
