Should coordinates for actions should support floats and not integer? #1690
Description
Right now coordinates for eg. pointer actions require integer values:
Let x be the result of getting the property x from action item.
If x is not an Integer, return error with error code invalid argument.
The question is if we still need this restriction or if it is unnecessary / unhelpful these days. Most users have a high DPI display where we can have multiple physical pixels per CSS pixel. In such a case we should probably really allow floats?
