SUMMARY
In order to work around an application bug, or just for customization fun, allow the user to set a per-application mouse cursor icon.

STEPS TO REPRODUCE
1. Encounter application bug where it scales cursor extremely incorrectly (to a tiny size) https://forums.factorio.com/viewtopic.php?f=7&t=120514
2. Attempt to create an Application Rule (Window Class exact match) to tell the application to use a larger cursor

OBSERVED RESULT
"Set custom cursor" isn't an available rule action

EXPECTED RESULT
I would be able to set a custom normal cursor image for a specific application program

Apps can also provide cursors at pixmaps. This would give us a window rule that wouldn't work reliably, most importantly in the cases where you'd actually want it.
