// end up being 300x300 and 150x300 in layer pixels.

// The second (child) layer has an additional CSS transform that
// stretches it by 2.0 on the x-axis. Therefore, after applying

// pixels.
//
// The screen itself is 24x24 in screen pixels (therefore 4x4 in
// CSS pixels). The displayport is 1 extra CSS pixel on all
