seems to work, still to do:

- tests
- try:

```
$ vipsthumbnail NordicsLIQUOR-SFBag_300_cmyk.JPG

(vipsthumbnail:7868): VIPS-WARNING **: 16:53:17.166: profile incompatible with image

d35343f817 stop making tiff pyr if axis drops to 1 
TIFF pyramids of images with a very extreme aspect raio could see layer
width or height drop to 0 before the image fitted in a single tile. This
change stops pyramid creation when width or height drop to 1.

ac4897abee Fix up vips_text() 
Fixes two issues:

1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.

2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.

e6f271df10 remove stop-at-solid feature 
We used to stop compositing when we reached the first solid image, but
that only works for modes like OVER.

Instead, composite all images, regardless of transparency.

3887d8a6e5 fix out of order read for some tiff 
Make sure we always have min of two strips in a linecache. Plane
separate tiffs with large rows-per-strip could shrink the cache to a
single block of pixels, which would then fail if the output straddled a
tile boundary.

See https://github.com/libvips/libvips/issues/1158

Thanks @chregu for the report.
