////////////////////////////////////////////////////////////////////////////
// Name: ScintillaWX.cxx
// Purpose: A wxWindows implementation of Scintilla. A class derived
// from ScintillaBase that uses the "wx platform" defined in
// PlatformWX.cxx This class is one end of a bridge between
// the wx world and the Scintilla world. It needs a peer
// object of type wxStyledTextCtrl to function.
