In the past, the base class implementation of this was used to descend
into subtrees and paint children. That is now taken care of by
StackingContext::paint_descendants() instead, and nothing used this.
This more clearly expresses the purpose of this flag. Since only
CSS::WhiteSpace::Nowrap sets this value to false and it does not respect
linebreaks, this made the most sense as a flag name.
This commit refactors the text chunking algorithm used in
TextNode::ChunkIterator. The m_start_of_chunk member parameter has been
replaced with a local variable that's anchored to the current iterator
at the start of every next() call, and the algorithm is made a little
more clear by explicitly separating what can and cannot peek into the
next character during iteration.
The code handling the rendering of the text-decoration-line got moved
into its own function to reduce clutter.
The CSS property text-decoration-line now supports underline, overline
and line-through.
Creating a ChunkIterator allows you to iterate over the text in a
Layout::TextNode at your leisure by calling next() when you want
another chunk.
This is one of many steps towards improving inline layout.

A label's format is: <label>Label text</label>
So, a TextNode is created as a child of the Label node, and EventHandler
will send events to the TextNode. This changes TextNode to accept mouse
events if its parent is a Label, and to forward those events upward.
The generic is<T>() uses dynamic_cast which is fine in the majority
of cases, but when one of them shows up in profiles, we can make it
faster by answering the is-a question manually.
