Raph's technique relies on compute shaders as a core part of the processing technique. That wouldn't work on an overwhelming majority of phones these days. Pathfinder has a compute-less approach which moves the binning to the CPU, not the GPU. And we're talking about bandwidth-constrained devices. I don't think you're going to out-perform H264. Slug is not applicable to this scene -- it makes several core operating assumptions (being able to pre-process curve data into a friendlier format, and its shape bounding boxes are well-defined and pre-processed. These hold for font / text assets but not real-time glyphs)
