maxPanOffsetHorizontal

The maximum horizontal pan offset relative to the dimensions of the ReaderView, defined as a CSS string in pixels or percentage.

Example: Setting it to "0%" will not allow the left side of the publication to be panned further right than the left side of the ReaderView. (and the opposite for the right side)

Example: Setting it to "50%" will allow the left side of the publication to be panned to the midpoint of the ReaderView. (and the same for the right side)

Example: Setting it to "100%" will allow the publication to be panned all the way outside the ReaderView.

NOTE: This options has no effect if IReaderViewOptions.transformManagerOptions.maxPanOffsetVertical has been set.
