scrollToMark
open fun scrollToMark(mark: TextMark, withinMargin: Double, useAlign: Boolean, xalign: Double, yalign: Double)
Scrolls @text_view so that @mark is on the screen in the position indicated by @xalign and @yalign.
An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If @use_align is false, the text scrolls the minimal distance to get the mark onscreen, possibly not scrolling at all. The effective screen for purposes of this function is reduced by a margin of size @within_margin.

margin as a [0.0,0.5) fraction of screen size
useAlign
whether to use alignment arguments (if false, just get the mark onscreen)
