Fix a alpha issue with RGB32 and DirectFB
Since we can't use RGB32 format with DirectFB (issues regarding Qt's
assumptions about the alpha byte) we need to explicitly convert images
of this type to the preferred alphaPixmap format.
This fixes an issue where RGB32 images get a curious gray alpha overlay.
