Don't cap the FEGaussian max kernel size.
Don't cap the FEGaussian max kernel size.

This is now wrong, since we now do all filter traversals in Blink in
world space, and filters don't know their correct device-space size
until playback time anyway (thanks to pinch-zoom and hidpi).

Skia will take care of applying the appropriate device-space limit.
