processPixel(callback, callbackContext, x, y, width, height) → {Phaser.BitmapData}
Scans through the area specified in this BitmapData and sends the color for every pixel to the given callback along with its x and y coordinates.
Whatever value the callback returns is set as the new color for that pixel, unless it returns the same color, in which case it's skipped.
Note that the format of the color received will be different depending on if the system is big or little endian.
It is expected that your callback will deal with endianess. If you'd rather Phaser did it then use processPixelRGB instead.
The callback will also be sent the pixels x and y coordinates respectively.
