It is likely that things can be done better.  An existing factor is 
that some formats are using external libraries (e.g. libjpeg, libpng, 
libwebp) and these provide their own error handling and reporting, 
even if they use I/O wrappers provided by GraphicsMagick.  These 
libraries often produce their own error codes and error strings which 
are not necessarily aligned or mapped into GraphicsMagick's own codes.

Formats like GIF are totally under GraphicsMagick control so there is 
no excuse if it does not report the problem, as long as the underlying 
operating system adequately reported it.  I think that GraphicsMagick 
should be able to report a useful error for WebP since it is 
responsible for writing the output from it.
