5f6911d516 add thumbnail_stream 
this works:

	$ cat k2.jpg | vips thumbnail_stream [descriptor=0] x.jpg 200
	$ vipsheader x.jpg
	temp-0: 141x200 uchar, 3 bands, srgb, jpegload

4d3f66fe33 add stdout write 
this now works:

	$ vips invert k2.jpg .jpg | vips invert stdin x.jpg

"stdin" means read from stdin, ".jpg" means write to stdout in JPG
format

71b557cfc1 remove "minimise" handler from tiffload 
We need to be able to disconnect the underlying fd and we can't do that
without making our own input handler for files. Implement this when we add
input objects.

1ef1b2d987 much faster handling of missing heif thumbnails 
Fetching the thumbnail from a heif image without a thumbnail used to
reselect the image for each scanline, which was horribly slow.

Thanks Kleis!
