Seprate color settings for theLines of TPO and Letters

1/ it would be possible to have the possibility of putting dark backgrounds with light letters just on the TPOC and TPO VAH and VAL, the problem is the lines which are too fine, so we put dark colors to see them , but then we no longer see the letters.

2/ be able to put thicker lines

3/ choose the color of the lines independent of the color of the background of the letters.

this is also valid for the lines of the profile volume VAL VPOC VAH
