[Scidvspc-devel] Patch1: Eval bar for boards, inturn Enabled for Analysis Board

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

Hi,

This patch adds generic support for showing eval bar wrt any specified
board. Inturn the same is enabled for analysis boards and the main
pv's score is shown as the evalbar.

Have implemented two different versions of eval bar, one is a simple
linear one and another is a combination of linear+logarithmic one.

The simple linear version shows the eval bar linearly wrt -4 to 4 with
clipping of values beyond it

The linear+log version shows a linear movement wrt -1 to 1 which maps
to being adjacent to the 4 and 5 rows, and a logarithmic movement for
beyond. The log values are mapped such that crossing 3 and 6 rows map
to be equivalent to gaining or losing a minor piece and 2 and 7 rows
map to gaining or losing 10 points, and remaining beyond.

Currently I havent tried to enable this for MainBoard. As one may want
to add an option entry to menu or buttons bar or ...
