Description
The current master does not appear to produce output via the fallback ICC profile. For example:
[kleisauke@pc-kaw ~]$ wget https://github.com/lovell/sharp/raw/master/test/fixtures/cielab-dagams.tiff
[kleisauke@pc-kaw ~]$ vips colourspace cielab-dagams.tiff cielab-dagams.v srgb
(vips:30470): VIPS-WARNING **: 13:54:35.304: Incompatible type for "RichTIFFIPTC"; tag ignored
[kleisauke@pc-kaw ~]$ vips icc_transform cielab-dagams.v x.v srgb --input-profile=srgb --intent=perceptual --embedded=true
(vips:30490): VIPS-WARNING **: 13:54:41.133: profile colourspace differs from image
icc_transform: no input profile
(same output with vipsthumbnail cielab-dagams.tiff --size 128 --iprofile srgb --eprofile srgb)
This worked fine on vips 8.7.4:
[kleisauke@pc-kaw ~]$ vips colourspace cielab-dagams.tiff cielab-dagams.v srgb
(vips:9654): VIPS-WARNING **: 14:01:24.103: Incompatible type for "RichTIFFIPTC"; tag ignored
[kleisauke@pc-kaw ~]$ wget https://github.com/libvips/nip2/raw/master/share/nip2/data/sRGB.icm
[kleisauke@pc-kaw ~]$ vips icc_transform cielab-dagams.v x.v sRGB.icm --input-profile=sRGB.icm --intent=perceptual --embedded=true
(vips:9794): VIPS-WARNING **: 14:01:28.219: embedded profile colourspace differs from image
See #730 for more background information regarding this cielab-dagams.tiff image.
