Coping paints take significant time. The ApplyFontToPaint
idiom requires a copy and a dtor. This CL keeps the paint and
font in parallel through the code until a paint is actually
needed, then a special ctor is used to create it.
Also, inline a bunch of text blob calls that were showing up
in perf.
