      Description

      Windows has two modes of touch input - pixel-based low resolution and sub-pixel-based high resolution which provides very precise position but causes a flood of events. Glass currently uses the high resolution, but rounds the coordinates to int values, so it combines the downsides of both modes.

      The sub-pixel resolution is most of the time not needed and it brings considerable performance problems, so we need to switch to the low-res mode. If there is a request for the other one we will provide it as an option in the future.
