no need to change this but it works without this too, right?

[enne (OOO), 2014/11/18 22:23:40]

No, it does not.  ResourceProvider does not end up using sync query and so
CanUseOneCopyRasterWorkerPool returns false.

[reveman, 2014/11/18 22:26:26]

I don't think there's a CanUseOneCopyRasterWorkerPool function anymore. One-copy
should now work even if this extension is missing.

When did it get removed?

[reveman, 2014/11/18 22:56:57]

Oh, it was removed by:

https://chromium.googlesource.com/chromium/src/+/9bc50696509edce28d25653b19ee...

but it looks like it was reintroduced by:

https://chromium.googlesource.com/chromium/src/+/03dbe8ae71dbf674627acad91fff...

I should have caught it when reviewing that patch, sorry. Do you mind fixing
this?
