Expensive: the browser blurs every shadowed particle again on every frame, and a larger blur costs
more (measured in Chrome: about 30 particles with blur: 14 dropped the frame rate to about 40 fps). For
glowing particles prefer blendMode: "lighter" or an image shape with the glow drawn in, like the
FIREFLIES preset. adaptiveQuality turns shadows off on slow devices. Trails are drawn without the shadow.
