About
Even after starting the LCD driver, the screen will not update until it is told to do so.
lcd.Draw
can be called at any time to copy the drawing buffer
to the display buffer. This is likely to happen when LameLCD
is already updating the physical screen, which will cause the
screen to flicker.
