Here's the above implemented as code.
To get Fl_Tile to act as a "resizer", it's important that the tile's
two children (the "hold" browser and the "group") have their common edges
/touching/ each other. This causes Fl_Tile to make this boundary mouse
sensitive to interactive resizing.
I was lazy and left out the two widgets at the lower-right, cause
their behavior will just be an extension of the others.
