Summary: pix_image support for TIFF incomplete

Initial Comment:
pix_image doesn't load certain images saved with Adobe Photoshop. The worst 
thing is that it doesn't print an error message and, sometimes (but not 
always), it even prints the success message: "threaded loaded image: xxx.tif" 
even if the image is not decoded.

I attach a tiff file saved with Adobe Photoshop that triggers this issue. Maybe 
the source of the problem is the existence in the file of a private tiff tag 
"37724" (Image Source Data) which is used by Photoshop. All images I tried that 
have this tag suffer from this issue. Unfortunately if you open one such image 
with Photoshop and save it again, there seems not to be any way to get rid of 
this tag (nor to know about its existance). Note that a lot of people use 
Photoshop under Mac or Windows to edit or create image files.
However I created other images from scratch with Photoshop myself and they 
didn't suffer from this problem (and they don't seem to have that tag). I don't 
know what determines whether Photoshop includes this tag or not in the saved 
image.

Anyway, as far as I understand (which is not very far) the presence of an 
unknown tag shouldn't be a reason for not being able to decode an image.
