Functions for wxGridBagSizer class

A wxSizer that can lay out items in a virtual grid like a wxFlexGridSizer but in this case explicit positioning of the items is allowed using wxGBPosition (not implemented in wx), and items can optionally span more than one row and/or column using wxGBSpan (not implemented in wx).

This class is derived (and can use functions) from: wxFlexGridSizer wxGridSizer wxSizer

wxWidgets docs: wxGridBagSizer
