Define Percentages too for GETMOUSEPOS

[Rainroom69]

Possible to also get the x and y percentages defined of the cursor position on the screen you are in, when you use $GETMOUSEPOS$ ?
I notice working with x, y position in pixels is not working well in case of different screen sizes. I do hope a solution with working with the percentages can solve this somehow when using it with $SETMOUSEPOS$ Am I right in this way of thinking ?
Thanks//
