Detailed Description:
-----------------------------
Run dnd, then resize larger than the window currently is (say to 700x700) and
move some of the flower patterns to the border of the window.
Resize window smaller and see that the flower patterns will be clipped quite a
bit after they should be. (See attached photo for example)


Steps to Reproduce:
----------------------------
1. start weston under X11 or DRM mode
2. ./dnd
3. Resize dnd window larger (say to 700x700)
4. Drag and drop flower patters to the edge of the window
5. Resize the window smaller and you should see the bug
