set_border is not working

[mattdesl]

The set_border colour is not working as expected for me. Below is a simple program in which I would expect the border color to turn white, but it doesn't.

#!/usr/bin/python
from PIL import Image
from inky import InkyPHAT

display = InkyPHAT("black")

def get_filled_image (color):
  img = Image.new("P", (display.WIDTH, display.HEIGHT))
  for x in range(display.WIDTH):
    for y in range(display.HEIGHT):
      img.putpixel((x, y), color)
  return img

img = get_filled_image(display.WHITE)
display.set_border(display.WHITE)
display.set_image(img)
display.show()

At first I thought this was some sort of hardware limitation, but while hacking around with the lookup tables I managed to get a pretty nice update that entirely fills the screen with black or white. To solve this, I created a new lookup table that, instead of drawing the correct black or white pixels in phase 3, just draws pure black or pure white pixels. The result is that the border finally turns white.

Looks like the register settings I was using for setting border colour were all kinds of wrong. I've tackled them with a bit of trial-and-error magic and come up with something that seems to work on Black, Yellow and Red units.
