Demonstration showing application of the Jump Flood Algorithm for realtime effects like model silhouette outline and glow. Based in part on the concepts described in this article by Ben Golus.

- Improved outline anti-aliasing referencing the above article.
- Limit the the jump flood operation range using stencil tests rather than operating on the full screen / scissor.
- Use lower precision textures.
- Investigate lower-resolution textures for jump flood stage, like half float - possibly requires using UV coordinates rather than pixel values.
