[platform-swt-dev] Improve Error messages from SWT

Hi,

Just because I looked at a JFace-Bug-Report today I noticed that the
error message given from SWT could be improved e.g. take this bug report
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=186325). The SWT-Error
given doesn't tell anything about the cause of the problem. I think the
problem is a disposed font but if the error message would have been:

------------8<------------
java.lang.IllegalArgumentException: Argument not valid (Font passed is
disposed)
...
------------8<------------

This would make spotting the culprit much easier. My question is now do
you think it is worth the effort and I should log a bug and provide
better error messages using SWT.error(SWT.ERROR_INVALID_ARGUMENT,null, "
(Font passed is disposed)").

Thanks

Tom
