Various improvements

Browse Source 
1)Use a new helper function for the drawing as the code was nearly identical at three different places
2)Fixes the coloring of transparent points : full color as intended, rather than black
3)Additional drawing points to properly manage the gauge_goal going outside of the gauge_full space
