* splash/SplashBitmap.cc: Make Splashbitmap RGB8 use 32bits internally
        * qt/poppler-page.cc:
        * qt4/src/poppler-page.cc: Adapt to splashbitmap change so copying to
        QImage is faster.
        Patch by Frank Meerkötter slightly modified by Albert Astals Cid

I'll leave adapting the glib frontend for you guys, i tried to adapt it but i got lost at gdk_pixbuf_get_n_channels (pixbuf);
