// Name:        stc.cpp
// Purpose:     A wxWindows implementation of Scintilla.  This class is the
//              one meant to be used directly by wx applications.  It does not
//              derive directly from the Scintilla classes, but instead
//              delegates most things to the real Scintilla class.
//              This allows the use of Scintilla without polluting the
//              namespace with all the classes and identifiers from Scintilla.
