/***********************************************************************************************
* SliderCtrlX
*
* Enhanced Slider Control / Slider indicator
*
* Autors : avpavp, jerson, jibe, koldo
* Last modified : June 09, 2011
*
* 2do : adjust default values when changing CONTROL/INDICATOR
* Better .usc file
* Known bugs : Invalid memory access when choosing FillColor with .lay designer (seems to be
* only with ubuntu. See http://www.ultimatepp.org/forum/index.php?t=msg&th=6022&start=0&
