The point-entered and point-left properties _must_ be handled in this
manner, because they're open ended -- users can add any sort of hook
they want, and such hooks might actually depend on this behavior.

The mode-line state (by contrast) only depends on the position of point
at the instant of redisplay, so recalculating every time point moves
will often be wasted effort.
