Actually,in a conversation with a game programmer,I found out that it isn't
as simple as rendering a white pixel needs rendering of all colours while
rendering a black pixel needs an absence of colours,thus power is saved.Even
the black pixel rendered is not true absence of colour but actually a mix of
the dark colours which is close enough to black for the human eye.So,power
saved is basically nil.

Sometimes,a few off topic discussions are ok,because otherwise,IMHO,there's
no life in a community when there's no healthy interaction on a wide variety
of topics,and you are stuck with "Topic1 and related"
