[Scidvspc-devel] Patch2: MultiPV traffic lights for boards, inturn Enabled for Analysis Board

[C H. M. <han...@gm...>]

Hi,

Eval bar gives position score wrt the main pv only, while with the
faster comps and engines and thus in turn multipv, there is additional
info like how good or bad or tricky a position is etc.

Inturn to show the same to user in a simple and straightforward way,
have added generic support for a additional bar next to eval bar,
which shows the scores wrt all the PVs in a MultiPV in terms of
Red-Yellow-Green traffic light summary wrt each PV, next to one
another. So by looking at the color pattern one can get a quick hint
has to whether the position is good or bad for white or black and also
how sharp or not the position may be and so.

The same is enabled for AnalysisBoard, which will be driven from the
corresponding engine's MultiPV.
