layout: added "inputraw" parameter, for use with inputtag and inputmask. It sets the element state directly to the raw input data & mask. Example uses: 8 way joystick state, multi-bitmask dipswitch state. If you don't want it to respond to layout mouse clicks, add a dummy inputtag rect under it. (nw)
