Subject: bypass GDKSplashOutputDev and just use a normal SplashOutputDev. Speeds

Wed Jan  5 15:38:28 2005  Jonathan Blandford  <jrb@redhat.com>

        * pdf/xpdf/pdf-document.cc (bitmap_to_pixbuf): bypass
        GDKSplashOutputDev and just use a normal SplashOutputDev.  Speeds
        things up a bit.

        * shell/ev-sidebar-thumbnail.c: start of some profiling code.
