mx, my, m_state, k_state: ivar

This function returns the current mouse pointer coordinates and the status of
the mouse buttons and the keyboard 'shift' keys.

This is an AES routine to query the mouse. Unlike MOUSEX etc., the function
gives valid results if the pointer is within a menu bar.

Return value will always be 1.

    mx      - Current x-coordinate of the mouse.
    my      - Current y-coordinate of the mouse.
    m_state - Mouse button status:
              Bit 0: Left button
              Bit 1: Right button
    k_state - Status of keyboard 'modifier' keys (if key is pressed bit is set):
              Bit 0: Right shift key
              Bit 1: Left shift key
              Bit 2: Control key
              Bit 3: Alternate key

The parameters mx, my, m_state, and k_state are optional, these values can
also be found by querying GINTOUT(1) to GINTOUT(4).

Memo: GRAF_MKSTATE() with no parameters crashes the compiler.
