Add support for the textArea element from TinySVG 1.2.
Merge branch '2.x' into textArea

* 2.x:
  Back out an inadvertent change to a commented line.
  Changed to query and use the ascent for the text offset.
  Undo change for vertical offset; I think it's bogus.
  Improve SVGTextElement to have support for text-anchor and fill, also adjust the vertical offset by the scale.
Rename to TinySVGTextAreaElement.
Fixed the file name in the header comment.
Merge pull request #205 from dgileadi/textArea
