Closes #16025.

Fix font size when using wxGraphicsContext with wxPrinterDC in wxMSW.

Use pixel size which is scaled correctly by GDI+ itself instead of the size in
points which is currently not scaled correctly by wx.

Closes #3566.

Add a helper function to get the last tree item to the sample.

This makes the behaviour of different menu commands working with the "last
item" consistent as some of them used the last root child while others used
the really last item (i.e. the last child of the last child).

This should have been part of r75987.

Fix wxGenericTreeCtrl::ScrollTo() for all ports, not just wxOSX.

When scrolling down, make the item being scrolled into view completely visible
instead of just showing its top part.

The fix was already used for wxOSX but not for the other ports for some
reason, do use it everywhere as this code is generic and behaves in the same
way in all ports.

Also fix the wrong comments about scrolling direction.
