viewportBoundsRange note has wrong lower bound

[qbojj]

In chapters/limits.adoc the viewportBoundsRange note is missing a '2' in the lower bound:

This would give a bounds limit of [eq]#[-pname:size {plus} 1, 2 {times}
pname:size - 1]# which would allow all possible non-empty-set intersections
of the output target and the viewport.

Should be

This would give a bounds limit of [eq]#[-2 {times} pname:size {plus} 1, 2 {times}
pname:size - 1]# which would allow all possible non-empty-set intersections
of the output target and the viewport.
