@brief Set origin of (0,0) and orientation of OLED display
@param r
The index for rotation, from 0-3 inclusive
@return None (void).
@note SSD1331 works differently than most (all?) other SPITFT
displays. With certain rotation changes the screen contents
may change immediately into a peculiar format (mirrored, not
necessarily rotated) (other displays, this only affects new
drawing -- rotation combinations can apply to different
areas). Therefore, it's recommend to clear the screen
(fillScreen(0)) before changing rotation.
