Description copied from interface: LeadingMarginSpan

Called when drawing the margin.

The default implementation is to call LeadingMarginSpan.drawLeadingMargin(icyllis.modernui.graphics.Canvas, icyllis.modernui.text.TextPaint, int, int, int, int, int, java.lang.CharSequence, int, int, boolean, icyllis.modernui.text.Layout), where x is either left or right, depending on dir.
