/* ************************************************ NOTICE ABOUT @grant ************************************************
Starting with version 10.0, GM_setValue and GM_getValue will be used to store the default SWF player that the user will set.
Previously, this was made using a separate user script because I liked the fact that this one did not require any specific permission.
In version 12.0, I have also added a preference for Ruffle's renderer since the default one, under certain circumstances, is apparently not always the best one.
With @grant none, the window object (and the related context in general) is freely available to user scripts (in Tampermonkey, at least).
However, granting access to certain GM_ functions such as setValue and getValue prohibits that. Therefore, I have to use @grant unsafeWindow, too.

Note for the future: with August 24th, 2022's update, the difference between AVM1 and AMV2 games is the "old" superNova code for AMV2 and the "new" Ruffle code for AMV1,
however the game shell is no longer mentionned there. This makes me fear that, if they implement one day Ruffle for every games, the difference between them may be VERY HARD
to make.
Fear confirmed on February 3rd, 2023.
Partial solution: using document.getElementById("gamediv").firstElementChild._metadata.isActionScript3.
Problem: this only works if Ruffle works...
Temporary solution: using the value of kongregate_api_path pasted in the HTML, as long as the value stays different between AVM1 and AVM2.

on https://github.com/colin969/Kongregate-Patched-APIs, this code must be defined in functions on the web page and the SWF must call these functions directly.
Kongregate updated their AS3 API accordingly at the end of November 2025 (but the AVM1 one has not been touched yet).
As of February 14th, 2026 (and since somewhere in December, if not the beginning...), the functions are missing from the Javascript side so the AS3 API is currently broken.
I will (re)define them here until Kongregate fixes that. */
