Jeff Epler 28bd29eb42 displayio: ColorConverter: fix logic errors about transparent pixels ... The transparent_color field was never initialized. I _think_ this means its value was always set to 0, or the blackest of blacks. Instead, initialize it to the sentinel value, newly given the name NO_TRANSPARENT_COLOR. This exposed a second problem: The test for whether there was an existing transparent color was wrong (backwards). I am guessing that this was not found due to the first bug; since the converter had a transparent color, the correct test would have led to always getting the error "Only one color can be transparent at a time".
