1868396 - Make VideoBridgeParent texture lookup threadsafe

Status: RESOLVED FIXED

(Core :: Graphics, task, P3)

Description

[Andrew Osmond [:aosmond] (he/him)]

If we make VideoBridgeParent texture lookup threadsafe, we can use it off the Compositor thread to do lookups on the CanvasRender/CanvasWorker threads. This will allow us to avoid copying data from the RDD into the content process, and back into the compositor process, when it has already been shared with the compositor process in the first place.
