`point`by adding the given amounts to its X and Y values.`dx`and`dy`must be integers. The results will be clamped to the range -2147483648 to 2147483647.If

`dx`and`dy`are already stored in an sdl2:point, it is more efficient and convenient to use`point-add`or`point-sub`, instead of extracting the individual fields from the point.`point-move`returns a new managed sdl2:point.`point-move!`modifies and returns`dest`. If`dest`is omitted,`point`is modified and returned.

Requires sdl2 egg 0.2.0 or higher.
