473	[PATCH] Zoom levels.	SpeedEvil	xeen	"Currently the zoom control has a few usability problems, especially on slow systems, or ones with uncertain mice.

Firstly, the zoom range is 4000Km-4m - which is a little uncontrollable. 
Clamping the maximum zoom to either the maximum extents, or 50* the current zoom would be an option.
Also the minimum zoom to 2% of the current zoom level.
Also, perhaps double-clicking (with a tool-tip to inform the user) to revert to the previous zoom level.

Just thoughts."	enhancement	closed	major		Core		fixed
