Just a quick question before I implement this myself:
My project has a decently low pixel-to-world-unit ratio, and I wanted to experiment with generating pixel-perfect meshes for my sprites to save on transparent rendering.
tk2d already does most of the heavy lifting: it will generate triangulated meshes from custom sprite islands. I don't want to go and outline by hand hundreds of sprites, though, so I need to automate the generation of the custom sprite meshes.
Does tk2d contain any code to automatically generate a pixel-perfect mesh outline to feed into the custom mesh builder?
