/*! \file wx/editor/sttool2.h
    \brief stack based tools for drawing and editing in a faster manner, but with less document feedback.

    Tools here are drawn directly via the drawing context, and not by first adding them to the document.
    This makes certain feadback drawing from the document impossible, but is much faster.
