	* app/[all files with resolution info]
	* libgimp/gimp.h
	* libgimp/gimpimage.c
	* libgimp/gimpsizeentry.[ch]
	* libgimp/gimpunit.[ch]
	* plug-ins/newsprint/newsprint.c
	* plug-ins/pgn/png.c
	* plug-ins/tiff/tiff.c: double instead of float for all resolution
	and unit-factor variables.

	* app/commands.c
	* app/crop.c
	* app/interface.c
	* app/layers_dialog.c
	* app/move_tool.c
	* app/resize.c
	* app/rotate_tool.c
	* app/scale_tool.c: pass the image's unit *and* gdisp->dot_for_dot
	to all functions which create sizeentries. Never create a
	sizeentry with UNIT_PIXEL but with the image's unit and set it's
	unit to UNIT_PIXEL after creation if dot_for_dot is on.
	This way the image's unit can always be picked from the menu
	without selecting "More...".

	* app/interface.c: made the query_*_box() functions use the
	ActionArea.

	* plug-ins/gimpunitmenu.c: GTK_WIN_POS_MOUSE for the unit
	selection dialog.
