Subject: [PATCH] PocketBook: use inkview to adjust image colors to look more
 bright (#9756)

Adjust image colors for PocketBook color devices to supply
brighter image colors. Make it a config option so we can
adjust it to a sensible default for all devices later.
Also enable HW Dithering for color devices: the dithering
flag allows us to figure out if what is viewed is an
image or text. This way we can enable color rendering
or not based on the dithering flag.
