commit f611f9580469661e585f419a7dd033ddffd7e20d
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>

sna/trapezoids: Difference between two 32-bit quantities is 33-bits in size
When computing the edge distance, we subtract on 32-bit quantity from
another. This requires 33-bits to store the full result so promote the
subtraction to 64-bits (rather than the result of that subtraction as
done currently).
