* 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.
It can not be skipped as you may call setwindow even if device is not ready for data write to buffer.
Data can only be written if last command was Memory Write or Write Memory Continue which was not guaranteed
There's no performance loss as having the exact same window on a consecutive call is extremely unlikely
- Fixed some typos and added a few missing comments to please go-lint
