Pretty good!  I'm still learning C++ and Qt, but I think I've been able to
figure things out and make some useful progress.

July is fairly open for me, and I hope to get most of the printing bugs
fixed by then.  After that, I'll be off to college, so I don't really know
how much time I'll have.

Now for a quick update...
I've gotten most of the print composer working with GraphicsView now.
Printing and image export are not working yet, but I'm hoping it won't be
too difficult with some of the new printing stuff in Qt 4.
As it turned out, porting to GraphicsView did not make the text
away. :-(  However, I think GraphicsView does make some things
and is worth doing.

If some other Linux users could run my font test program below, that would
be helpful.  Let me know your Linux distro, Qt version, and whether the text
came out garbled.
A Linux binary is here: http://botsnlinux.googlepages.com/QT_Fonts , and
source code is here: http://botsnlinux.googlepages.com/QT_Fonts.zip

After I get the port completed, I hope to move onto some other
improvements.  Should I just work on some the the bugs and enhancements
listed in trac<http://svn.qgis.org/trac/query?status=new&status=reopened&component=Printing&order=priority>or
is there another list somewhere?  Should there be an e-mail and/or
forumpost asking for ideas and most wanted improvements?
