[Splashy-devel] Translucent Text Area Patch.

[Luis M]

Hello Pat,

You blow my mind everytime you submit one of these patches...

Thanks a lot!

I couldn't figure out how to do this, and certainly NOT how to do it
properly. I'll backport this patch "by hand".

Note that we have made the build process a lot better now. You will be
able to quickly make a debian package from dist .bz2 tarball. Greatly
reducing confusion and other friction that might arise. But, i
understand that you can't simply use upstream sources for the project
you are working on.

Keep the patching coming none-the-less. Perhaps later you will have
time to re-sync and we will try our best not to do major changes to
the code (in svn) without a previous consensus from vendors using
splashy (like is your case -- Xandros, otavio's custom distro, demarc
security solutions, and some others that skip my mind now).

This should definitely encourage others to do the same, and  can focus
in getting other things that matter as well (feature requests, bugs,
and maintaining the IRC community alive).
