public interface TextDrawingCallback

IDEA editors use highly-optimized drawing algorithm that is tuned for painting large amounts of text data.

However, there is a possible case that particular editor extension or third-party component may want to draw text at IDEA editor on it own. It's not supposed to do that directly, contrary, it's expected to delegate the processing to the code that knows how to do that.

Current interface defines a contract for such a text drawing delegation task.
