I would like to change chromium's ImageDiff to reflect the magnitude of
pixel changes. Currently, if the pixel has any difference, the entire pixel
is marked as 100% red. I'd like to change it so that miniscule difference
are 20% red and large differences are 100% red. Looking at the code for CG,

The GTK and Efl produces a grayscale image, where the pixel goes from
black (no difference) to white, gradually, propor

Perhaps generating a list of rectangles where there are differences
would help produce s
Food for thought... Skia's "skdiff" tool generates two diff images for each
image pair:
- 1. every pixel which is different at all between images 1 & 2 shows up
as white
- 2. every pixel shows the color difference between images 1 & 2 (much
more subtle)
