ParagraphBuilder class
Builds a Paragraph containing text with the given styling information.
To set the paragraph's alignment, truncation, and ellipsizing behavior, pass an appropriately-configured ParagraphStyle object to the new ParagraphBuilder constructor.
Then, call combinations of pushStyle, addText, and pop to add styled text to the object.
Finally, call build to obtain the constructed Paragraph object. After this point, the builder is no longer usable.
After constructing a Paragraph, call Paragraph.layout on it and then paint it with Canvas.drawParagraph.
