RGB Panels have higher pixel density than neopixels

• RGB Panels have higher pixel density than neopixels
• But pixels have no local processing, panel requires constant refresh
• Only 4 bits per RGB, 12 bpp when GFX supports 16bpp
• Originally written by Adafruit for 32x16 panels
• Supports 32x32, 64x32 on some CPUs, but not above
• Was able to port my GFX demo and run the same code on NeoMatrix and RGB Panels
