I think this is actually a bug in our implementation of 
BFont::TruncateString() and/or our BView/BFont::StringWidth() methods. This 
code worked just fine on BeOS and I've seen other places in Haiku where 
code in one place calculates the necessary width with StringWidth() and 
then code at another place uses TruncateString() with that exact same width 
and string and what happens is that the string gets truncated even though 
it should not be. I'd rather leave I-O-M allone and fix the actual bug.

This Transformer is pretty useless. Plus, while it does something, I know 
that in certain situations it can behave badly.

This one is not implemented at all.

"Freeze Transformation" is actually useful. When you have transformed a 
shape, and you go back to editing one of the paths assigned to the shape, 
you will see that the paths are still at their untransformed location. 
"Freeze Transformation" will apply the current shape transformation to all 
the assigned paths (and styles too, BTW) -- provided that no other shapes 
reference the same paths/styles! -- and reset the shape transformation back 
to identity. Before you say that the path could be displayed at the 
transformed location, it is often also useful to keep displaying it 
untransformed (because of more convenient snapping perhaps). Plus when you 
edit a path, you don't know with what shape you want to be looking at it.

I would keep both features, but I-O-M could hide this from the user and 
automatically pick the correct attribute name depending on the location of 
the file. If it happens to be inside the MIME database, it would use 
META:ICON. To be honest, I am currently working on other stuff and don't 
want to work on I-O-M right now.

Yes, for exactly this purpose. It's very easy to implement too, if someone 
feels like looking into this. However, the menu also serves as a label, so 
I would just keep it as it is. I-O-M is not finished, in this particular 
case I'd not like to hide this fact. :-)

I can remove the two useless Transformers from the menu.
