What's new in Osmose 0-9-96:

Osmose now owns a clean graphical user interface based on QT. QT was the first
GUI i found, powerfull enough to refresh display at 60hz. So SDL is no more used now.

-Switch sound system to use ALSA
-GUI development using QT.
-Rendering / Key mapping adapted to QT OpenGL.
-Configuration system rewritten.
