Render Painted Layer Blob respects m Valid Region but does not update it
There is this line in WebRenderPaintedLayerBlob::RenderLayer: > regionToPaint.Sub(mVisibleRegion.ToUnknownRegion(), mValidRegion); Are we intentionally excluding the current valid region from the region to paint? Or do we always want to paint the whole layer? We're currently not updating mValidRegion to include the drawn region after at the end of RenderLayer(), so it's possible that mValidRegion is just always empty here. In that case, subtracting it from the visible region won't make a difference. But it's still confusing.
