// line/column. The original Robot.text(), or the more low level
// print() function can only set text position on pixels from left,
// top.
//
//- The process of accepting input with the virtual keyboard, saving
// into or reading from EEPROM is delt with here.
//
//- A workflow for stop the music while displaying image. Trouble
// will happen otherwise.
