Subject: pdf/splash/SplashBitmap.cc (SplashBitmap, ~SplashBitmap, writePNMFile):

* pdf/splash/Splash.cc (clear, drawPixel, drawSpan, xorSpan, getPixel)
(fillGlyph, fillImageMask, drawImage):
pdf/splash/SplashBitmap.cc (SplashBitmap, ~SplashBitmap, writePNMFile):
pdf/splash/SplashTypes.h:
pdf/xpdf/SplashOutputDev (startPage, getColor, imageSrc): implement RGB8
packed mode for Splash.

* pdf/xpdf/GDKSplashOutputDev.cc (GDKSplashOutputDev, redraw): use
RGB8 packed mode, eliminates the pixbuf data creation loop.
