improve more the isBusy background case

--the new implementation supports and always darkish
case when the isBusy background is drawn. So now
we have the following possibilities:
a)panel transparency<35 means BEST contrast with
underlying desktop background
b)panel transparency>=35 AND <70 means a DARKISH
background
c)panel transparency>=70 the user chosen plasma
theme
