Feel free to kick this PR into a lake if it's not considered useful (or if you're already doing this somewhere and I didn't catch that). I think its useful that SDL already provides this as part of it's input subsystem, so this PR exposes includes the relative mouse position as part of the input state.
yeah I think getting the raw mouse delta can be useful for situations where you want the mouse to control a camera... I may tweak this afterwards but I'll merge this in, thanks!
