This regression doesn't come from a pattern colorspace, this PDF code is
handled wrong:

Cs1 is a ICC based colorspace. I looked at it, and either the clip rectangle is
calculated wrong or the starting textposition. I would expect that it is the
clip rectangle, because it seems as if the position of the displayed text is
okay, but I'm not an expert in this part of SplashOutputDev.
And finally PSOutputDev with my path handles this page correctly.
Are there any other experts in this? I fear it will take a long time for me to
find and correct this error!
