Automatic update from web-platform-tests [OT-PW] Make it work with OOP-R This CL makes off-thread paint worklet work with OOP-R. OOP-R serialize an PaintOp and stores the serialized buffer in a shared memory. GPU then reads the memory and de-serialize it. For off-thread paint worklet, we are producing a DrawImageRectOp. Note that this DrawImageRectOp is different than a normal one. It is a DrawImageRectOp that contains a DrawRecord that contains multiple PaintOps in it. So this CL adds a special code path to serialize it, for paint worklet DrawImageRectOp only. The way to serialize it is to iterate over all the PaintOps inside the DrawRecord. In this way, we do not need to change anything on the GPU de-serialize code. We also changed the layout tests. We changed some tests, now using fillRect instead of strokeRect. The problem with strokeRect is that using GPU rasterization could easily result in subpixel difference on different platforms. Using fillRect will avoid that.
