Is there a Paint.net plugin to create a spriteatlas (aka spritetexture or spritesheet)? A sprite atlas is used in game development, and it's a single image that contain several smaller images of game objects, sprites, enemies, particles, animations etc. Instead of loading many tiny images a game typically uses a sprite atlas so it can be loaded as a single texture, which improves loading time and game performance.
So I mean a plugin that takes several images, or maybe the layers of an image, and neatly packs it into a spriteatlas/sprite texture, plus generate the accompanying coordinates file.
I had already created a similar plug-in for GIMP, see here:

Is something like that available for Paint.net? Or a related question, where do I start if I want to develop a plugin for Paint.net?
