Support MinSize and MaxSize for resizable extension #8
Description
A manifest.xml file can have MinSize and MaxSize tags in Geometry tag like Size tag for building resizable extension. Specification is here: CEP 8#extension-size, CEP 9#extension-size.
I want to use this feature and I think it is not difficult because they are same with panelWidth and panelHeight. I'll send a pull request for it.
