Subject: Make thumbnail image decoding async
X-Git-Tag: 1.34.0-rc.0~3199^2
X-Git-Url: http://git.cyclocoop.org/%28?a=commitdiff_plain;h=4a79eefc78e6c9c782bf946b8be01803734f0635;p=lhc%2Fweb%2Fwiklou.git

Make thumbnail image decoding async

This is a browser hint indicating that decoding of the image can be done
asynchronously (instead of synchronously during the image's onload event).
Marking decoding as async enables the browser to display any other
non-image content that might be waiting to be rendered, without waiting
for the image to be decoding. This should allow text to appear sooner in
some situations, where the browser would have otherwise waited to
bundle its rendering with an image. The final result (non-image + image
content being displayed) will happen at the same time as before.

Given how text-heavy wiki context usually is, it makes sense to allow
users to see the text sooner in some situations, so they can start reading.
