[PE]: Improve the interest rect computation under perspective.

This patch tries to normalize some of the rects we deal with when
performing interest rect calculations. This is done by capping the
ranges of numbers that we may encounter, in order to produce more
stable results.

The upside of this is that we will paint more content that we would
otherwise erroneously assume to be not intersecting the viewport
(even after padding).

The downside of this is that we may paint more content that is properly
far off screen.
