-- set res_unit meta in im_tiff2vips, then use that to set res unit default in
-  im_vips2tiff

-- setting :res_inch as a tiff option does not multiply by 2.54 :-( ie.
-
-	  1 pixel per mm vips image
-	  save as a tiff with res_cm
-	  sets 10 pixels / cm
-	  save as a tiff with res_inch
-	  sets 10 pixels / inch ... wrong!

-- test, backport to 7.14

 - should check for gettext in configure? see
