In the mean time I've done some more work on this, and added some more
widgets. menus, combo-box, tooltip, label and meter widgets been in
place now. Also I've added a LV2 plugin example which show how easy and
lightweight the creation of a LV2 UI could be.
Yea, and all is documented in the Docs.

Yea, I've made the experience that I never ever do any documentation
"afterwards". So this time I would do it from the beginning on. At least
it helps as well myself, to not forgot what it is about.
However, today I make a big step regarding transparent widgets. Those
who've done any development with X11 and cairo knows that it could be
tricky.
Today I find out that the big difference is to NOT USE
cairo_image_surface_create. Avoid it. When working in a X11 context, the
way to go is cairo_surface_create_similar on the xlib surface as buffer.
This avoid unnecessary coping the image data from the graphic server to
CPU and back. The CPU footprint boils down to below 2% on full screen
action here. Even on resize action, when the surfaces needs to be
resized/destroyed and new created.
Before this change CPU could reach 80% and more and the desktop starts
to stutter.
However, I've setup a online Documentation
for libxputty here:

And *that* is the best news of the lot!
So many projects have little or no documentation until they are a
very long way
into development.
