Of course You're true once again, even if I like the effects of setting a
minimum line width in this case. But when regtesting it, I encountered such a
lot of changes, most of them look better, but some of them look worse, that I
broke the regtest and had a deeper look in the code. And I found the problem:
Even if pathAllOutside in Splash::fillWithPattern says, that the line is
partial inside, when the XPath is created and antialiased,
state->clip->testRect later on says that the line is all outside. The problem
seems to be in SplashXPath::SplashXPath, where adjust and strokeAdjust moves
the line out of the clip area, if the line is very thin.
But I need more time to solve it completely and don't break other renderings,
so I'll come back when I find a clean solution.
