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`

Look at all items and see if any intersect (or would overlap) the given item.

Returns true if so, false if there would be no overlap. If an `excludeItem` is given then it will not be checked for intersection, for example it may be the item we are checking the position of.
