* Unify the Rotation type, so that SetRotation can be used in
interfaces.
* Add Rotation() method to these displays, so that the current
rotation can be read.
* Change SetRotation() so that it can return an error (if the given
rotation isn't supported).
The API looks like this and is based on the PCA9685 PWM chip:
Sleep(sleepEnabled bool) error
It will set the LCD panel to a low power state (not displaying any
image) but memory contents will be preserved.
This is needed for high performance graphics.
Using this API, and using partial updates to the screen (no full screen
refreshes), I've been able to get well over 60fps of updates.
Most of the ceremony around pin toggling was in fact unnecessary. This
improves performance measurably (rougly 6% in one measurement) and cuts
down on binary size by 80 bytes.
