/* 
From Romain Lievins(?) :
   Most of these definitions and code comes from the JB's SkinEdit
   which is based on TiEmu skin code. TiEmu skin code is also based on
   VTi's skin code.
   
contra-sh :
   This file is a (quasi ?) perfect copy of the tiemu skinops.h file ...
   Thank's to Romain Lievins and Julien Blache for this wonderful work.
