Detailed Description

The image manipulated by the emulation.

This class implements the operations of the terminal emulation framework. It is a complete passive device, driven by the emulation decoder (TEmuVT102). By this it forms in fact an ADT, that defines operations on a rectangular image.

It does neither know how to display its image nor about escape sequences. It is further independent of the underlying toolkit. By this, one can even use this module for an ordinary text surface.

Since the operations are called by a specific emulation decoder, one may collect their different operations here.

The state manipulated by the operations is mainly kept in `image', though it is a little more complex bejond this. See the header file of the class.
