Detailed Description

A virtual textlayout.

This class wraps the QTextLayout used for rendering. Modifying all cursor/positioning related methods, supporting single-cursor items, while rendering multiple QTextLayout characters

Note: this is very Edbee specific. Every TextLayout has got a single line!
