Announce: SmartMatrix::GFX

I just had time to port a bunch of demos to SmartMatrix thanks to the new API layer, see

marcmerlin/SmartMatrix_GFX/blob/master/README.md

SmartMatrix::GFX, Control Scan Based Matrices with SmartMatrix and Adafruit GFX API
===================================================================================

Please have a look at this blog post for more details and pictures:

for details, how these panels actually works have a look on this sparkfun post.they have a nice article if you want to understand in depth.

Adafruit_GFX and FastLED-compatible library for RGBPanels (row scan matrices).   
This library requires FastLED and Adafruit_GFX libraries as well as this base class library:
- https://github.com/marcmerlin/Framebuffer_GFX
Please look at the Framebuffer_GFX page for details on how the APIs work and you can also look the example demo code:
- https://github.com/marcmerlin/FastLED_NeoMatrix/blob/master/examples/MatrixGFXDemo/MatrixGFXDemo.ino

Example demo code: 
https://github.com/marcmerlin/FastLED_NeoMatrix/blob/master/examples/MatrixGFXDemo/MatrixGFXDemo.ino388

This library requires SmartMatrix, Adafruit_GFX, and FastLED libraries.

Demos:

Those demos should work with both SmartMatrix::GFX and FastLED::NeoMatrix thanks to the compat layer.

@Jason might notice the irony that I ported Aurora demos back from SmartMatrix to GFX and then back to SmartMatrix
https://github.com/marcmerlin/SmartMatrix_GFX/tree/master/examples/Aurora
but this version is “better” in that the demos have been split in independent demos that can run on their own, and can be moved from SmartMatrix and to NeoMatrix with a single #define in the top level config.h
