I can't really comment on the math but

+       v.vector[0] -= (pixman_fixed_e * v.vector[2]) >> 16;
+       v.vector[1] -= (pixman_fixed_e * v.vector[2]) >> 16;
+       unit.vector[0] -= (pixman_fixed_e * unit.vector[2]) >> 16;
+       unit.vector[0] -= (pixman_fixed_e * unit.vector[2]) >> 16;

Shouldn't the last line be "unit.vector[1]"? Also, I'd put the common
subexpression in a local variable but maybe that's just me.

"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
