SpectorJS broken in Chrome Canary due to new, lower postMessage size limit

[kenrussell]

Chrome version: 63.0.3236.0 (Official Build) canary (64-bit)
OS: macOS 10.12.6 on Retina MacBook Pro, NVIDIA GPU

To reproduce :

1. Load https://webglsamples.org/aquarium/aquarium.html
2. Record a frame from the canvas via Spector.js
3. The record will fail to display.
4. Open the console

It contains:

Uncaught Error: Message length exceeded maximum allowed length.

Hello @kenrussell

Thank for the feedback. Are you aware of anything I could/should use in Canary to share a huge amount of data with an extension ?

Also What is the current limit ?

I will fix it as soon as we agree on the best strategy for this. I hope I won t have to split the capture to make the extension work.

Thx

if you find a different way to send data to extensions, it might help with #63

I just stumbled upon this: https://github.com/krakenjs/post-robot Do you think this could fix the issue?

[sebavan]

I ll have a look at it, thx. I will wait the answer to this issue before integrating #63 .

Happy to report that I found a small and localized fix for this problem. :)
