Force rasterfallbacks with a env variable in dfb
If qgetenv("QT_DIRECTFB_FORCE_RASTER").toInt() > 0 all paint operations
will fall back to the raster engine in DirectFB. Good trick for
debugging.
I hijacked the compositionModeStatus variable for this since it's
checked for every paint operation anyway and I didn't want to introduce
any overhead.
