Well happy to help test, but seems above my technical water line.

Wade experimented (and there are patches in trac I think) with a pulse animation effect that was quicker to transition but then paused slightly at max/min. Seem to remember it took another ~couple of seconds off startup, but never made it through to a release (was part of his work on the activity startup failure message that did thankfully land).

I didn't think any of Glucose used numpy? I thought it was there for Fructose (Activities) only if they needed. FWIW I have a couple of Activity projects that would use numpy but I'm not there yet.

Pre-rendering is tricky as both stroke/fill colour, and image size are variable.

I was hopeful after seeing Mart Raudsepp's email a week ago to the dev list about Cairo's slow rendering on XO hardware (and possible future improvements), but Wade pointed out the pulsing animation is currently a Hipocanvas thing.
