* Move waypoint screen draw into the waypoint module
* Get the observer set up for the waypoint screen draw
* Static squashing: screen dimensions
Macros moved back to Screen.cpp, as a band-aid until we eventually move all those static functions into the Screen class.
* Move getCompassDiam into Screen class
(supress compiler warnings)
At this stage, the method is still static, because it's used by drawNodeInfo, which has no tidy reference to our screen instance.
This is probably just another band-aid until these static functions all move.
* Use new getCompassDiam function in AccelerometerThread
* Properly gate display code in WaypointModule
