Support for Mouse & Mouse Api

[RobDavenport]

We should support mouse inputs in addition to the keyboard/gamepad.

This would be limited by pixel coordinates.

Some discussion points: -InputState is using almost all 64 bits already.

• If we add pixel-based coordinates, we would need to support up to 1920 x 1080, which needs 11 each to represent the width & height. Plus two more for the buttons. Minimum 11 + 11 + 2.
• Do we also want to support mouse wheel? 3rd mouse button? Or should we reserve these other 8 bits for system flags, like reset buttons?
• We could increase input state to be either 128 bits (64 + 64), or 96 (64 + 32) and use separate API calls for mouse states.

    pub fn mouse_middle_held(player_id: i32) -> i32;
    pub fn mouse_x(player_id: i32) -> i32;
    pub fn mouse_y(player_id: i32) -> i32;
    pub fn raw_mouse_state(player_id: i32) -> i32;

Is the current API we're looking at. Additionally I'm investigating how to handle mouse wheel/scrolling

[RobDavenport]

Currently the API now looks like this:

    pub fn mouse_left_pressed(player_id: i32) -> i32;
    pub fn mouse_left_released(player_id: i32) -> i32;
    pub fn mouse_left_held(player_id: i32) -> i32;
    pub fn mouse_right_pressed(player_id: i32) -> i32;
    pub fn mouse_right_released(player_id: i32) -> i32;
    pub fn mouse_right_held(player_id: i32) -> i32;
    pub fn mouse_middle_pressed(player_id: i32) -> i32;
    pub fn mouse_middle_released(player_id: i32) -> i32;
    pub fn mouse_middle_held(player_id: i32) -> i32;

    pub fn mouse_x_pos(player_id: i32) -> i32;
    pub fn mouse_y_pos(player_id: i32) -> i32;

    // Raw mouse information, works even when locked
    pub fn mouse_x_delta(player_id: i32) -> i32;
    pub fn mouse_y_delta(player_id: i32) -> i32;

    // This is only a boolean value if the wheel moved in this direction or not
    pub fn mouse_wheel_up(player_id: i32) -> i32;
    pub fn mouse_wheel_down(player_id: i32) -> i32;
    pub fn mouse_wheel_left(player_id: i32) -> i32;
    pub fn mouse_wheel_right(player_id: i32) -> i32;

    // Locks it for the PC attached to that player
    pub fn lock_mouse(locked: i32);

    pub fn raw_mouse_state(player_id: i32) -> i64;
