Basic resizing issues

The min size / % size thing should be sorted now.

Thanks for the quick changes! After I synched I noticed a slight hick-up while resizing. As if there’s some kind of threshold value before a component increases size when it’s on the minimum size.

This shows the issue more clearly when slowly resizing the height from small to big:

<vbox width="100%" height="100%" style="padding:5px;">
    <hbox width="100%" height="20%" backgroundColor="0xff0000" style="min-height:50px"/>
    <vbox width="100%" height="60%" backgroundColor="0x00ff00" style="min-height:50px"/>
    <hbox width="100%" height="20%" backgroundColor="0x0000ff" style="min-height:50px"/>
