scrollTo
Moves the pane to x, y in view coordinates, coerced to what the content reaches.
The coercion is against the metrics of this moment, so a block running before the content has been laid out writes 0 and follows the content as it grows. While no pane renders the state there is no content to coerce against, and the position is taken verbatim.
Parameters
x
the view coordinate to show at the viewport's left edge, coerced into 0..maxX.
y
the view coordinate to show at the viewport's top edge, coerced into 0..maxY.
