New patch

The patch of bug 19670 still has some holes, see
http://www.alfa.de/2285316_1_4.pdf and
http://www.alfa.de/hires3758404382736598728.pdf
So I attach a new path to solve this issues. The several parts are

1. Function.cc
In http://www.alfa.de/hires3758404382736598728.pdf there was a regression in
PSOutputDev.cc under windows, because the domain variables were not initialized
and therefore results in random double values i.e. in func3->getDomainMin(0)
2. Gfx.cc
a) When changing in a BT/ET bracket from pattern colorspace to a nomal
colorspace (s. 600 NEUE HITS in
http://www.alfa.de/hires3758404382736598728.pdf) with operators opSetFillGray,
opSetFillCMYKColor or opSetFillRGBColor, we first need to fill already placed
text.
b) In opSetFillColorSpace the fill pattern is removed to early, we first need
to fill the already placed text.
c) Because of the above changes, colorSpaceText and colorText are not needed
anymore and are removed in Gfx.h, too.
3. SplashOutputDev.cc
The patch of bug 19670 for colorizing image masks with pattern colorspace does
only work correct in PSOutputDev.cc, not in SplashOutputDev.cc. So I completely
redesigned the implementation

Best regards,
Thomas
