EVENT_LOGGING

A variable controlling whether SDL logs all events pushed onto its internal queue.

This variable can be set to the following values:

• "0" - Don't log any events (default)
• "1" - Log all events except mouse and finger motion, which are pretty spammy.
• "2" - Log all events.

This is generally meant to be used to debug SDL itself, but can be useful

for application developers that need better visibility into what is going

on in the event queue. Logged events are sent through SDL.log(), which

means by default they appear on stdout on most platforms or maybe

OutputDebugString() on Windows, and can be funneled by the app with

SDL_LogSetOutputFunction(), etc.

This hint can be toggled on and off at runtime, if you only need to log

events for a small subset of program execution.
