iOS & Canvas Garbage Collection

[sandstrom]

I noticed this iOS issue, which mentions that canvas garbage collection doesn't work unless canvas width/height it set to 0 after use.

I'm not saying this is something that should be implemented, but I'm curious if you've heard about crash issues when using Pica on iOS? If so, I just wanted to mention that this may be the reason.

I don't remember such issues. That's strange.

Not something that needs to be tackled, necessarily. I can see the downside of trying to patch a hole we don't know exist, or can't easily verify exist.

But just wanted to put this out here, since it may be relevant.

@puzrin Wow, that was quick 😄
