Change default shape color

<http://cgit.freedesktop.org/libreoffice/core/commit/?id=895890563cb0cc5fa872bdfd06918a46cdda172d> 
"Change default shape color" breaks the build (cf. e.g., 
<http://tinderbox.libreoffice.org/cgi-bin/gunzip.cgi?tree=MASTER&brief-log=1354168201.15043> 
Linux-RHEL6-x86_64_14-with-check log).

I do not know whether we really want that (the commit message gives no 
rationale, and I think to remember there were already attempts to change 
that before that ultimately got reverted again, for reasons I cannot 
remember), so am unsure whether the better fix is to unbreak the failing 
test or to revert the commit.
