I've just wrote a simple downsizer plugin. It's both a test for the new WM Pro PDK, and a component of some plugin I am developping right now. I don't know if the device can be useful in any meaningful ways, but since there is yet a resizer to appear in WM Pro, I thought it might be useful. I've also included the source in case you want to see yet another example (project built with VC 2003). Just put it in the Beta 5 PDK folder and you should be set.
