Hi,

attached is a patch that fixes clip-fill-{eo,nz}-unbounded for me. The problem
is that the X server estimates the bounded extents of the drawing and it does so
with some rounding error. The result what you can see in the test failures.

I hope this makes sense and that this is the right fix. It's the best idea I had
so far.


One thing that I am not sure about is if this should really check for
!extents->is_bounded.
Perhaps this only needs !(extents->is_bounded & CAIRO_OPERATOR_BOUND_BY_MASK)?
Is there any difference between the two at all?

Cheers,
Uli
