The gimp_drawable_type() is an issue though as gimp_drawable_get_type()
is already defined as a common GObject API.
Though I'm actually wondering if GimpImageType is well called. Rather
than Type, shouldn't we go with ColorModel?

sed -i 's/\<gimp_drawable_bpp\>/gimp_drawable_get_bpp/g' "$@"
sed -i 's/\<gimp_drawable_width\>/gimp_drawable_get_width/g' "$@"
sed -i 's/\<gimp_drawable_height\>/gimp_drawable_get_height/g' "$@"
sed -i 's/\<gimp_drawable_offsets\>/gimp_drawable_get_offsets/g' "$@"
