throwable field which holds the underlying
exception that caused the problem (if this information is
available (i.e. it may be null)).
SWTExceptions are thrown when something fails internally, but SWT is left in a known stable state (eg. a widget call was made from a non-u/i thread, or there is failure while reading an Image because the source file was corrupt).
