wxWidgets/contrib/src/stc/ScintillaWX.cpp
Robin Dunn 719493e14b On wxMac don't call Refresh from FullPaint as that is the biggest 
cause of the performance problems.  Instead call refresh when the
AutoComp window is displayed or hidden to ensure that borders,
etc. are drawn/erased as needed.

// 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.
