/*
Layout change code concept by Baruch Rutman
peterooch~AT~gmail~DOT~com
Needs <winnls.h> to be included for SetProcessDefaultLayout, GetUserDefaultUILangauge
and <wingdi.h> for SetLayout
Mostly recommended to be added before any window drawing!!!
maybe can get added to the winnls.h,wingdi.h or something else,
the language detector works great, the functions need some refinement.
