* \brief Process the user interface

* This function processes user touch events and updates the display.
*
* The first registered touch is used to control the cursor. Its presence is
* indicated with a red frame around the display. When the cursor touch moves,
* its movement is visualized with a trace on the display.
*
* The second registered touch is used to control mouse buttons, and is
* indicated with an inner frame of which the color depends on which side the
* touch is for: blue for left and green for right button click. The frame is
* shown until the touch is released.
* To detect which side click it is, the position relative to the cursor touch
* is used, i.e., a touch to the left of the first touch will cause a left
* mouse click.
*
* \param framenumber Current USB frame number
*
* \note This function should be called every millisecond, e.g., for each USB
* frame.
