pitrix/effects.h
Fabian Schlenz 0e82f94846 Lots of changes:
* More animations with generalized code to display them.
  * The hostname will now include a unique id of the ESP.
  * Effect can now be restricted to a smaller "window".
  * Clock is now BigClock, SmallClock is now Clock.
  * Clock shows the time as well as the sinematrix effect. Closes #8.
  * If the loop takes too long too often, the ESP will automatically be rebooted. Closes #12.
  * The text drawing methods are now much more generalized. #5.
