MZ Resource Rescue

Introduction
This plugin cleanly reuses Bitmaps across Map transfers and to an extent other ImageManager resets, which can significantly reduce load times. Bitmaps and textures are still destroyed shortly afterwards, so memory use should at most spike a little bit on those occasions.

(I may eventually include other resource types, so the plugin name is generic. The plugin is named such because it "rescues" resources that are already slated for garbage collection or would be destroyed explicitly.)

Features
There's a debug option to log Bitmap resource management details to the console, but it's pretty noisy.

You can also adjust when Bitmaps can be explicitly destroyed through the JavaScript API.
Normally this is not necessary outside of Map transfers though, for which this plugin suspends Bitmap destruction by default.

Screenshots
If all goes well, Resource Rescue has no visual effect at all, aside from the loading spinner not showing up as much or as long.

How to Use
Save the plugin file into your js/plugins folder and enable it in the Plugin Manager. (There are effectively no settings.)

Plugin Commands / Script Calls
The API is namespaced as TS_Resource_Rescue and for now includes version and parameters objects, an overridable isSuspended() method to delay explicit Bitmap destruction and old…/new… entries (trampoline pattern) for all installed hooks.
