Just submitted a patch for a slightly faster gaussian blur: https://github.com/vrld/shine/pull/27 It's about 1.5x-2x as fast (depending on number of taps) for basically identical output. You can also set a larger offset than 1 for low entropy images. For example I can do { taps = 11, offset = 2 } at...

Did you ever get good performance from a blur shader on Android? I'm finding that `shine.gaussian` blur at least works, but the performance isn't good enough to use. At sigma 5, I drop from 60fps locked to ~5fps. `shine.boxblur` can manage 50fps with radius 2, which is still neither fast enough nor ...
