Windows cursor deletion off

*Created by: sampottinger*

Filing for [kll](https://discourse.processing.org/u/kll) from a [processing forums discussion](https://discourse.processing.org/t/processing-in-style-with-java-11/13776/24). There is a report that deletion happens at the wrong position on Windows with no zoom, Monospaced, 10pt. Possibly related to #19.
