Documentation: clarify how hidpi affects mouse scaling #10074

Closed expikr closed 1 week ago

expikr commented 1 week ago

README-hidpi.md does not mention anything about how display scaling will influence SDL's mouse input scaling.

There should be a comprehensive clarification about how each hint and dpi configuration interacts with the events which are posted, with concrete cases for various game types (FPS, hardware-cursor RTS, software-cursor rhythm games etc) and how users can set their OS settings or envvars to override developer oversights.

It does not affect mouse input. Those units don't change.

A comprehensive guide sounds good, but probably not something we'll have time to write as we work towards SDL 3.0 release. Please feel free to create a PR with one you've written.
