Prawn::Rtl::Support

This gem provide bidirectional text support for Prawn. It uses Unicode Bidirectional Algorithm for displaying text from TwitterCldr::Shared::Bidi and connect arabic letters using Arabic Letter Connector. Prawn patching is minimal, we patch only Prawn::Text::Formatted::Box#original_text.
