NeoMatrix code not compatible with SmartMatrix, so I wrote http://github.com/marcmerlin/SmartMatrix_GFX

• NeoMatrix code not compatible with SmartMatrix, so I wrote http://github.com/marcmerlin/SmartMatrix_GFX
• Now all my demos work both with NeoMatrix and SmartMatrix backends: https://github.com/marcmerlin/FastLED_NeoMatrix_SmartMatrix_LEDMatrix_GFX_Demos
• Now I can re-use all my existing code and demos and they just work on SmartMatrix: Adafruit::GFX, FastLED, NeoMatrix, and LEDMatrix.
• I ported some SmartMatrix code down to NeoMatrix (SmartMatrix API is more complex and unused by demo code I’ve found)
• New Shirt should be ready for EDC 2019 and Burning Man 2019
