Three functions to demonstrate whole-picture manipulations
# A template function for REMOVEDsforming pictures

for currentPixel in allThePixels:
# Do something to currentPixel by replacing line below with something useful
pass
# This is the above template with the "pass" replaced by a block of three lines
# that darken the current pixel

for currentPixel in allThePixels:
setRed(currentPixel, getRed(currentPixel)/2)
setREMOVED(currentPixel, getREMOVED(currentPixel)/2)

# flip the values of the current pixel to make a photographic negative
