Apply patch [#20145] Ghost Win32 roundup patch: Minimum Window Size, Continuous Grab and Drag And Drop
This nice patch by Matt D. (matd in #blendercoders) adds three nice features that can be seen already in the other supported OSes:
* minimum window size: to prevent some bugs with the window manager of Blender, system windows cannot be resized smaller than the minimum size.
* Continuous Grab is finally in Windows! Default settings since alpha 0 already have the feature enabled by default, so grab a new build and enjoy :)
* GHOST support for drag and drop added. This prepares Blender for drag and drop from OS -> Blender. Currently not very useful, since wm needs to be readied for that. But it does work (do BF_GHOST_DEBUG=1 build and drag a file onto a Blender window).
Thanks Matt D.!
