Re: [ft] FT_Done_Face Should Not Return An Error

[suzuki toshiya]

I guess, if the original request were something like:
"there are so many existing applications which ignore the errors from 
FT_Done_Face or FT_Done_Library.
I know no concrete examples of these errors, I want to collect the information 
on these errors, so I want to have some hook into these functions.
something like a registration mechanism of a function pointer to be called when 
FT_Done_Face or FT_Done_Library is going to return some error.
how to do that?",
the discussion could be more constructive.


Some desktop applications on Unix systems are expected to be running from the 
user's login to the user's logout. Some of them are depending FreeType. Thus, 
making FreeType abort immediately by a bad font, it can make some environment 
quite inconvenient.

# I remember, Mac OS X 10.0 had such problem. A bad font in user's font 
directory can prevent the login itself. It was quite inconvenient, except of 
the people knowing SSH or CUI login method.
