 // configured resolution of the display is not always the same as the touch
 // screen's reporting resolution, e.g. the display could be set as
 // 1920x1080 while the touchscreen is reporting touch position range at
 // 32767x32767. Touch radius is reported in the units the same as touch position
 // so we need to scale the touch radius to be compatible with the display's
 // resolution. We compute the scale as
 // sqrt of (display_area / touchscreen_area)
