I added this to the README. Eventually we will need a real
documentation for Splashy and the wiki page should be made available
in the distribution itself. For now, I updated the README with a few
things for the impatient ;-)

Ok.

I already added a section for this in the default theme's config.xml.
I hope you are keeping track of the latest development in svn. I'm
trying my best not to break svn at all cost... but sometimes after
hours of going through the source, i just smerge things so that i can
work from a different location the next day ;-) Usually is code I
leave commented out.

LOL. That's funny. Well, I have not have any success with the overlay
myself. I fired an email to directfb-users, but, no response. I guess
that is because this is such a well known issue that there is no need
to say it again... However, I've done a lot of research and I haven't
found a way to do it yet. I might have to actually read the whole
directfb documentation to figure this one out.

I already know how to capture the console. I'll put that in the
overlay when I get one working (I'll read /dev/vcs). I was just
thinking that having the "pring <string>" support in
splashy_functions.c would encourage others to submit patches to get
the whole thing working faster (many people have requested this
feature in the past).

Well, let's hope that by Saturday we have something working... I have
sample code that draws a surface and a window overlay. It works like a
charm. But I can't get the same functionality in the current Splashy.
This, i believe, is because Splashy is using a surface (with no
window) to do it's magic (and setting the whole thing to full-screen
mode, which makes it even harder to have windows). If I force Splashy
to go to window-mode earlier, like before the app actually draws the
image, then the resolution becomes about 1/4 of the screen (old, known
issue that I solved by doing a lot of magical things). Oh well...

It just burns me to have a problem that goes on for so long...

Thanks for your help anyway, and keep the patches flowing.
