[PATCH 1/8] perf: Guarantee path width is non-negative

This quells the following warning:

  perf/micro/hatching.c:39:5: warning: cannot optimize loop, the
  loop counter may overflow

Width and height aren't going to be negative so enforce it so that the
compiler can do whatever optimization it wants to do.
