I see your point.
My concern is that there are many GUI frameworks like
Win32, X, etc. They already have their own "look and
feel" for the standard UI controls (buttons, etc.)
I believe that the library should provide a way to use
the standard controls as is. So we'll need to define
a much bigger set of ingradients.

I agree that one can derive other required ingradients
from the ones that you listed, but it'll be your own
"look and feel". In any case the proposed libary
should not be focusing on the drawing issues at all.
For example if it needs to create a list control. It
should just call the GuiTraits::create_listconrol(...)
function. It won't care how it is implemented.

On the side note.
It seems that there is a significant interest in such
a library. I'll try to setup a sourceforge project.
I invite anyone to join. Stay turned.
