DirectFB 1.5: API
Extensions and API changes in DirectFB 1.5
IDirectFBGL2 and IDirectFBGL2Context
These two interfaces allow applications to create OpenGL rendering contexts and render to DirectFB surfaces or use them as textures.
This is a new rendering interface for advanced 2D bitmap and 2.5D vector graphics, so far.
There will only be one window stack, instead of one per hardware layer. CreateWindow() can be called from IDirectFB directly.
