- try making vips_add(), an operator as a class

can we write a find-by-nickname function? eg.

would get us the GType for VipsInterpolatorBicubic
add a g_get_children( "classname" ) -> ["child1-name", ..] to nip2, see old
vips8.c code?
in nip2,
inter = g_object_new "yafrsmooth" [$sharpness => 2.4];
also need something to return a list of GTypes below a name etc., find class
description:w
need k
- vips_object_print, set_name etc. need writing
- im_buf_t -> VipsBuf
now always included in vips.h
- check mosaic1, global_balance, similarity etc. use of im__affine
how can we move them to im_affinei ?
