Avoid incorrectly using EXTEND_NONE

It seems like we sometimes end up using EXTEND_NONE unintentionally, this is likely caused by different rounding between cairo and pixman. Pixman already does a similar reduction to EXTEND_NONE so there's not point in duplicating it here.

This is totally safe, considering it's just an optimization, but it sure doesn't make me happy.

Don't forget to add it as a cairo patch.
