Largest contentful paint test images
====================================

The images in this directory prefixed with `lcp-` are specifically intended to
be used by tests where a largest-contentful-paint entry should be generated. As
Chromium has implemented a contentfulness threshold of 0.05 bits per pixel,
these images, when rendered at their natural dimensions, have a minimum content
length, as shown in the table below:

File            | Dimensions | Area (px^2) | Minimum content-length (bytes)
