Support for full screen tagging

[breandan]

According @bulenkov, most or all String painting can be traced through Graphics2DLog (other places to look: Graphics2DLog, DrawString/DrawChars). If this is the case, we can search/tag all UI text on the screen (ie. not only editor text, but menus, toolbars, stack traces, etc). edit: Bypass rendering stack altogether, let's capture raw pixels and run OCR, then draw bounding boxes. Then we can simulate a mouse click in the desired region to "select" the tag.

Implementing this feature should also support tagging for multiple editor windows simultaneously.

edit: See this SO Question for implementation details.

Development on this feature has migrated to TraceJump, a full-screen implementation of AceJump. Closing.
