Shader-Glow Issues on iOS Safari

[mtmckenna]

Hello! Thanks for sharing these Three.js examples. They're super helpful.

I was wondering if you had thoughts on the Shader-Glow example--with a c of 0 and a p of 5.0, the borders of the glow looks great on desktop Chrome/Safari/Firefox. However, on mobile Safari on iOS, the transparency doesn't seem to work (screenshots attached). Any ideas? Thank you!
