ts_test - A basic test routine for tslib.

       ts_test  is  used  to  manually  test tslib using ts_read(). It draws a crosshair and mode buttons to the
       framebuffer and lets you test the behaviour of input samples with your configured  filters  applied,  see
       ts.conf (5). Since it uses ts_read(), it supports single touch only.
