Bug scrub: Does anyone know if this is working correctly with mash? When I boot a device with --enable-features=Mash things look mostly OK, but a black shelf shows up briefly before the login screen.

I'm not sure what BootSplashScreen is -- it doesn't exist in the code.

I think that BootSplashScreen was an old X11-era hack that copied the Chrome OS boot splash screen into a layer so we could fade smoothly from it to the login screen. I don't think that it's relevant anymore.

If there's jank during the boot-to-login transition with --enable-features=Mash, it should be fixed (why are we showing the shelf?), but it'd probably be better to use a separate bug for that.

+jdufault in case this isn't already on his radar.

This was a separate regression that should be fixed.
