On the subject of GDB, we have been hacking some GDB 7.0 Python for
printing WebCore types.

See this file:
  http://src.chromium.org/viewvc/chrome/trunk/src/tools/gdb/webkit.py?view=markup
This makes it so GDB can natively print types like
WebCore::AtomicString or WebCore::QualifiedName, including when they
are arguments to the function you've just broken into.  I find myself
now casting other UTF-16 strings (like, those used by Harfbuzz) into
UChar* when using GDB so it can print those types too.


I guess this file should probably live in the WebCore tree somewhere.
I hadn't gotten around to it because I wasn't sure where it belonged.
If anyone has a good idea where it should go I'll commit it.
