`point-unscale``point``factor`procedure`point-unscale!``point``factor``#!optional``dest`procedureEfficiently divide the X and Y values of

`point`by`factor`(a float or integer). This is equivalent to`(point-scale point (/ 1 factor))`, but is more convenient and efficient (especially if`factor`is an integer).These procedures signal an exception if

`factor`is 0. sdl2:point can only hold integer values, so the results will be truncated to integers. The results will be clamped to the range -2147483648 to 2147483647.`point-unscale`returns a new managed sdl2:point.`point-unscale!`modifies and returns`dest`. If`dest`is omitted,`point`is modified and returned.

Requires sdl2 egg 0.2.0 or higher.
