Display of map in geometry filter (especially inline mode)

[silvester-pari]

Currently, the map in inline mode is barely usable: it is very wide and most of it is initially hidden by scroll, then when you scroll over it it "captures" the scroll, it has no zoom buttons, etc.

Possible improvements:

• consider limiting the size of the map (horizontally)
• disable automatic scroll zoom by default
• add zoom controls
• intersect/within option: maybe overlay over map or find some better suited place (maybe better displayed as switch)?
