Research direction
Start by compiling and running the RasterParticleExample, then reproduce the blocky particles while zooming in at moderate levels. Trace the RasterParticleLayer rendering path used by that example and compare the result with the attached image. Done means particles remain visually smooth rather than becoming blocky when zoomed.
