Addition of highlight transparency

Added a small tweak to the Annotation class to do some transparency modification to get the highlight annotation to render without obscuring the text behind it.

The text in question is actually there, you can see it with text selection however it is covered up by the yellow highlight annotation. The red strikeout displays with out problem as it is supposed be drawn above the text. There is nothing in the specification on how the annotation should be drawn with regards to text. Normally annotations are drawn above the page content. We could probably do some special handling for highlight annotations which would add some transparency tot he fill. Arguable such an effect would be closer to what would be expect when highlight text with a highlighter?
