Rather than using the DOM to upload text and styling information into the engine, this patch begins sketching a more direct API that bypasses the DOM and CSS. Currently, this API doesn't do anything, but it's a first step. The approach is to have a ParagraphBuilder object that can record a tree of style interior nodes and text leaves. The build() function then applies container-level styling information (such as TextAlign) and returns a Paragraph object that can undergo layout and paint. The inputs to the builder process are immutable style objects constructed from primitive values. These primitives are currently carbon-copies of the primitive we use in the framework today. After this patch lands, I'll convert the frame to re-expose these values instead of re-defining them.
