patch against 0.18.0 (after applying the patch for bug 41374)

The postscript generated by pdftops gets errors on tiling patterns with
PaintType 2.  In PaintType 2 patterns, the pattern is uncolored, and you set
the color when you use the pattern.  The level 1 version created a font and
used setcachedevice (which builds a color into the font) instead of
setcharwidth.  The level 2 version didn't push the current color on the stack
which lead to a stack underflow error.  When the setpattern operator is called
with a pattern with PaintType 2, it looks for the paint color on the stack.
