Android : Pixel Format again. Transparent or Translucent pixel format should not be the deault setting as they drain a substential amount of fps and that most of the games will have an opaque background.

There is now a new ogles configType called BEST_TRANSLUCENT if users really want a transparent background.
The BEST or FASTEST confing are now both OPAQUE, this gives a nice boost to the BEST configuration.
