[Andreas Müller]

| Splash.cc:1497:30: error: conversion from 'SplashCoord {aka FixedPoint}' to 'Guchar {aka unsigned char}' is ambiguous
| Splash.cc:1497:30: note: candidates are:
| In file included from SplashMath.h:27:0,
|                  from Splash.cc:44:
| ../goo/FixedPoint.h:45:3: note: FixedPoint::operator int()
| ../goo/FixedPoint.h:43:3: note: FixedPoint::operator double()
