Summary: wxTreeCtrl::GetNextVisible() assert

Initial Comment:
by it's behaviour, GetNextVisible() asserts when a non-visible item is passed to it. It does its check using IsVisible that Sends TVM_GETITEMRECT to see if an item is visible before calling TreeView_GetNextVisible().
if the item is not visible it asserts.
THAT's a BUG. because: TVM_GETITEMRECT returns false when an item is even partialy visible, and TreeView_GetNextVisible() wont fail on such item.

Why is it important? because when customizing the tree GetNextVisible is important, I had to go around and use TreeView_GetNextVisible() myself, and that's not wxWidgets.

Why is the IsVisible assert so important anyway?
