Although clutter has a number of functions in the ogl space that can load texture from files, there are no functions to load data from pixbuf and create a temporary file for the pixbuf is an overkill.

In this wiki you either will find information about the different project I have done or, more importantly, documentation about frameworks I have used and hows documentation I have found limited or lacking in some way. Indeed, is this documentation is of any used, it should go to the documentation of such frameworks but unfortunately getting the permissions etc.. takes too much time and effort to do right now. If you find the documentation useful and want to move it …
