	* app/channel.[ch]
	* app/commands.c
	* app/gimage_mask.[ch]
	* app/gimage_mask_cmds.c
	* tools/pdbgen/pdb/gimage_mask.pdb
	* app/interface.c: propagated the indepentent x/y values for
	shrink/grow/border to the interface but not yet to the PDB.

	* app/*_select.c
	* app/paint_funcs.[ch]: implemented indep. x/y feather. It seems
	that cut-and-paste was sufficient, but I didn't really understand
	the code. Jay, could you have a look at this please?

	If the feather/shrink/... amount is specified in pixels,
	everything behaves like before.
	I'm not sure how the built-in feather option of the selection
	tools should behave, so it still defaults to 'pixel' mode.
	Moved the static feather/shrink/... values from gimage_mask.c to
	commands.c because they belong to the interface.

	* app/text_tool_cmds.c
	* tools/pdbgen/pdb/text_tool.pdb: prepared for resolution
	support, but didn't enable it yet.

	* app/unit_cmds.c
	* tool/pdbgen/pdb/unit.pdb: fixed a help text.
