This class now contains all the fun bits about laying out text in a rect. It will handle line wrapping at a certain width, cutting off lines that don't fit the given rect, and handling text elision. Painter::draw_text now internally uses this. Future work here would be not laying out text twice (once actually preparing the lines to be rendered and once to get the bounding box), and possibly adding left elision if necessary. Additionally, this commit makes the Utf32View versions of Painter::draw_text convert to Utf8View internally. The intention is to completely remove those versions, but they're kept at the moment to keep the scope of this PR small.
