This patch implements `Range::getClientRects` and `Range::getBoundingClientRect`. Since the rects returned by invoking getClientRects can be accessed without adding them to the Selection, `ViewportPaintable::recompute_selection_states` has been updated to accept a Range as a parameter, rather than acquiring it through the Document's Selection. With this change, the following tests now pass: - wpt[css/cssom-view/range-bounding-client-rect-with-nested-text.html] - wpt[css/cssom-view/DOMRectList.html] Note: The test "css/cssom-view/range-bounding-client-rect-with-display-contents.html" still fails due to an issue with Element::getClientRects, which will be addressed in a future commit.
