get-avg-pixel
given an array of pixel data not unlike that returned by canvasContext.getImageData().data, returns the data for the average of all of the pixels as {r: 0-255, g: 0-255, b: 0-255, a: 0-255}
EXAMPLE
/// ... canvas/context setup code up here ... \\\\\\
var pixels = ctx.getImageData().data
var getAvgPixel = require('get-avg-pixel')
getAvgPixel(pixels)
// => {r: 100, g: 212, b: 53, a: 183}
// now do something with that pixel data
