These variables are:
- populated to something besides RGBA_8888 only on Android
- don't come from the ICC profile (and may be at odds with the ICC profile) on
Android
- correspond to WebScreenInfo data.
- it eventually becomes query-able in JS

So, we can't get rid of color_depth and depth_per_component :(
