Robin Dunn 5fa4613c81 Added ability for wxSTC's scrollbars to be supplieed externally, such
as those that are created in wxDynamicSashWindows,

// 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.
