i'm in. :) just to be sure - this is about:

wm+cm now provides both frame AND window background (or is able to via its own
frame styles) and application + toolkit now provides ARGB windows with what
used to be the "window background" be transparent "assuming" it is composited
onto the wm+cm provided background. so this means that wm+cm and toolkit need
to at least agree on some content matters - like "contrasting colors" of wm
base and toolkit widgets (labels etc.) and of course agree on how toolkit/app
is to know this feature exists and can be provided, and then how the app will
request it for the purpose of getting a "seamless" frame+title+app+bg
experience. (the rest is just mechanics on agreeing on atom names to use, where
to stick properties and what they mean and which data to expose/fetch where in
what way).

am i on the same page?
