Fix paint worklet hidpi
Right now in the PaintRenderingContext2D::setTransform, we account for
the device_scale_factor_. This is wrong. It appears that internally
the recording canvas handles the device scale factor in the correct way.
Instead it should account for browser zoom.A layout test has been changed to expect the correct result.
Screen recordings here to show that the demo is rendered correctly:
