Re: [orion-dev] Why is ruler offset by lineHeight ?

[Silenio Quarti <Silenio_Quarti@xxxxxxxxxx>]

It looks like a bug, that should not
be the case.  I believe the same rulerStyle (this._rulerStyle) is
used to create both rulers and OverviewRuler is altering that object instead
of making a copy.

Every ruler div has one extra div at the top (firstChild before any lines).
This div is used to determine the width of the ruler. Its height is "lineHeight".
 The ruler is offset by "lineHeight" to hide this div above
the editor. 

Ok, thanks, that's fine, I can just add +1 to the line
to move my annotation down. Now how can I control the width of that div?
 

If I understand the design correctly, the UI has, from
left to right, annotationRuler, lineRuler, (client and overlay), overViewRuler.
The overViewRuler width seems to control the annotationRuler
width. That is if I set style.width = "140px"; in to OverviewRuler.prototype.getStyle
in the lineIndex === undefined, then both rulers are 140px wide.
