- Updated documentation for Input mouse modes.
- Change so that Input::GainFocus restores previous mouse mode.
- Fixed a bug where setting mouse mode in Input::LoseFocus was concealing the mouse visibility.
- Change so that SetMouseVisible tracks the intended visibility when MM_RELATIVE forces it off. This information is used to correctly set mouse visibility when changing mouse modes.
- Updated editor drag editing so that the cursor position is always at 0.
