Opacity of crosshairs.
This option sets the opacity of the crosshair lines. It does not affect the
opacity of the coordinates text label. The value of this option should be a
value between 0.0 and 1.0, with 0.0 being completely transparent and 1.0
being completely opaque.
To specify the opacity of each crosshair line independently, use the
crosshairs_opacity_h and crosshairs_opacity_v options.
