+Most of the Meshtastic firmware uses preprocessor macros throughout the code to support different hardware variants.
+NicheGraphics attempts a different approach:

+Per-device config takes place in this setupNicheGraphics() method
+(And a small amount in platformio.ini)
+
+This file sets up InkHUD for Heltec VM-E290.
+Different NicheGraphics UIs and different hardware variants will each have their own setup procedure.
