* Bars made full width, channel + name on left side, output value on right side. Background color added.
* Reverted redefinition of chanString, background color changed to BARGRAPH_BGCOLOR
* Added borders around bars
* Added BG border configuration. Refactored RECT_OFFSET into RECT_BORDER to allow easy change in border thickness.
* Fixed vertical line offset.
* BG settings affecting actual BG, not the border
* Fix for issue with trackpad & mouse wheel: Small movements up or down send delta=0, causing always events in the same direction.
