+/*-------------------------------------------------------------------------
+ Arduino library to control a wide variety of WS2811- and WS2812-based RGB
+ LED devices such as Adafruit FLORA RGB Smart Pixels and NeoPixel strips.
+ Currently handles 400 and 800 KHz bitstreams on 8, 12 and 16 MHz ATmega
+ MCUs, with LEDs wired for various color orders. Handles most output pins
+ (possible exception with upper PORT registers on the Arduino Mega).
+
+ Written by Phil Burgess / Paint Your Dragon for Adafruit Industries,
+ contributions by PJRC, Michael Miller and other members of the open
+ source community.

+// The order of primary colors in the NeoPixel data stream can vary
+// among device types, manufacturers and even different revisions of
+// the same item. The third parameter to the Adafruit_NeoPixel
+// constructor encodes the per-pixel byte offsets of the red, green
+// and blue primaries (plus white, if present) in the data stream --
+// the following #defines provide an easier-to-use named version for
+// each permutation. e.g. NEO_GRB indicates a NeoPixel-compatible
+// device expecting three bytes per pixel, with the first byte
+// containing the green value, second containing red and third
+// containing blue. The in-memory representation of a chain of
+// NeoPixels is the same as the data-stream order; no re-ordering of
+// bytes is required when issuing data to the chain.
+
+// Bits 5,4 of this value are the offset (0-3) from the first byte of
+// a pixel to the location of the red color byte. Bits 3,2 are the
+// green offset and 1,0 are the blue offset. If it is an RGBW-type
+// device (supporting a white primary in addition to R,G,B), bits 7,6
+// are the offset to the white byte...otherwise, bits 7,6 are set to
+// the same value as 5,4 (red) to indicate an RGB (not RGBW) device.
+// i.e. binary representation:
+// 0bWWRRGGBB for RGBW devices
+// 0bRRRRGGBB for RGB
