Fix OG_CustomCtrl hpos computation for CoPointpatch-3

Problem : 
* coPoint contain 2 windows in a sizer, and window() return only the first 
* OG_CustomCtrl check only the window() and so miss the second one

solution:
* OG_CustomCtrl now check if the field has a sizer, and if so get all sizes from inside, like the correct_widgets_position method
