[cairo] another pixman issue

[Robert O'Callahan]

See attached test program. With pixman-0.9.6-43-gddfb69a, which includes
Søren's "adjust" fix, the first row of pixels is
8d8d8d8d bebebebe bebebebe bebebebe bebebebe bebebebe bebebebe bebebebe
00000000 00000000
So I wonder why in this case we're sampling outside the source image. I
thought the purpose of "adjust" was to subtract an amount equal to half the
size of a *source* pixel from 'v', but it appears to not be doing that.

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
53:5-6]
