It's really not as low level as you'd like but have you considered using
Linked from http://www.galago-project.org/ but I cannot access just now
for some reason.
It is a DBus based Freedesktop standard for passive popup style
While it cannot do fancy GL based overlays I've for a long time wanted
someone to create a "theme" for it that makes use of a compositing
manager to make the "notifications" much nicer - transparent etc. etc.!
You can already time you notifications to disappear automatically (with
a countdown timer if you desire) and also embed buttons with callbacks
etc. when clicked.
It would be nice if your project could fit in somehow with this
framework and give something back that would benefit other applications
Just a thought.
