DirectFB cleanups & simple window manager
- use SDL_getenv, not getenv ...
- no more support for 0.9.25 - not even mentioned any longer on directfb.org
- fix fullscreen issues
- add a simple window manager unless the directfb team comes up with a working wm.
The driver has support for a very, very basic window manager you may
want to use when runnning with "wm=default". Use
export SDL_DIRECTFB_WM=1
to enable basic window borders including icon support. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf
