	* app/display/gimpdisplayshell.[ch]: Store the zoom factor as
	float, not as a ratio.

	* app/display/gimpdisplayshell-scale.[ch]: change the API to
	expose the Float instead a weirdly encoded integer. Implement
	functions to get a ratio from the scale factor. Implement a set
	as presets as discussed on the mailinglist. Changed Zoom->Other
	dialog to enable entering a float.

	floats instead of weird integers.
