`background-size` per CSS-BACKGROUNDS § 3.9.
Nearest neighbor interpolation is used for `crisp-edges`, like Firefox.
A note has been added that we could do better if we wanted to.
Multiple backgrounds are not yet supported.
Move culling of transparent display items to paint task rather than display list builder, so that hit testing detects mouse over on transparent background elements.
Sometimes, the root pipeline title is sent before the compositor has created the root pipeline, so also request the main page title once the initial frame tree has been sent.
Also introduce a clear() function to layout data which will be used to clear items such as compositor layouts.
Clear the layout data when a node becomes display:none.

When an iframe is created with display:none it sets the root layer to be zero width and height. When updating the rect of the iframe from layout send the entire rect rather than just the new origin, which handles the case where the iframe has been made visible and now has a non-zero rect.

Inline fragments that are part of a text run don't have interior borders.
So don't draw interior borders or include them when calculating positioning.
Fixes https://github.com/servo/servo/issues/4658, where multiple text nodes that are adjacent have distinct borders.
r? @Ms2ger, @pcwalton
Instead of looking at the boundaries of the text run, set the border
width to zero and the border style to none on border sides that are not
the outermost for a node container that is display: inline.
Prior to incremental layout, the code would remove the existing
construction result. However, with incremental layout the construction result
is cloned rather than removed. This change ensures that the previous
construction result is cleared when an element's display type
changes to none.
