--fix brightness calculations for vertical edges
for the desktop backgrounds
--improve debug messages for the brightness calculations
at BackgroundTracker
--Latte should remember 300 backgrounds
maximum and afterwards that cache is removed.
That way we can avoid cases that because
a slideshow plugin uses too many wallpapers
does not make Latte to have high memory usage.
--the luminas functions didnt work well
for all cases. Latte is now using brightness
functions as described at:
https://www.w3.org/TR/AERT/#color-contrast
this patch fixes all cases mentioned in the bug
that Latte contrast identification did not work well
BUG: 402115
--Latte now does not only identify background files
but single colors also. At the same time the new
implementation is multi-screen aware. That means
that two different top panels at two different screens
can be color independent, meaning the first could
be lightish when it is transparent and the latter
darkish
BUG: 402143
