Profile where i enabled the WPF rasterizer : https://share.firefox.dev/3JQqRf6 (5 second)
gfx.canvas.accelerated.aa-stroke.enabled = false
gfx.canvas.accelerated.stroke-to-fill-path = true

This is as fast as the skia-canvas version. So, AA-gpu-canvas thingy appears to be the slow thing here?

Jeff, this looks like because we don't support AA-Stroke when an alpha < 1 is used...

Profile from latest Nightly:

Gpu-canvas: https://share.firefox.dev/3N0xfAK (5.5s)
skia-canvas: https://share.firefox.dev/3XbDvKV (4.6s)

So this has improved a lot. There is some new PwebGL:Message_GetFrontBuffer at the end that takes 2 seconds.
