Replace a bisect with a single multiplication when calling
screen_get_dpi() in Javascript
Tested the value of
window.matchMedia(`(resolution:${(window.devicePixelRatio*96).toFixed(100)}dpi)`).matches
which is true except for values that cause a lot of rounding errors
(e.g. dpr : 0.3 => resolution: 28.799999999999997dpi)
Even in these cases the value matches the result of the previous
`findDPI()` method.
