/**
 * Mouse state. 1 is primary mouse button (e.g. Select on RISC OS).
 *              2 is secondary mouse button (e.g. Adjust on RISC OS).
 *
 * \note click meaning is different for different front ends. On RISC
 *       OS, it is standard to act on press, so a click is fired at
 *       the same time as a mouse button is pressed. With GTK, it is
 *       standard to act on release, so a click is fired when the
 *       mouse button is released, if the operation wasn't a drag.
 *
 * \note double and triple clicks are fired alongside a
 *       BROWSER_MOUSE_CLICK_[1|2] to indicate which button is used.
