What do I mean by this? I mean for anything that is dependent on the platform node-pixi is running within, it should allow for setting those references to something else. For things like window, document, or Image constructor references.
Also, duck-typing should be used in as many places as possible to avoid any more unnecessary platform specific references.
If this module is indeed deprecated, can you , in the docs of the module (not just the repo) point to the right version? Your module comes up in organic search and npm search before the official module. I spent some time looking for the correct one, as I am sure others will too.
