In GYP, we have the following in common.gypi:

        # Flags to use pango and cairo.
        ['OS=="win" or OS=="mac" or OS=="ios" or OS=="android" or embedded==1', {
          'use_pango%': 0,
          'use_cairo%': 0,
        }, {
          'use_pango%': 1,
          'use_cairo%': 1,
        }],

In GN, we have the following in ui.gni:

if (is_linux && !use_ozone) {
  use_cairo = true
  use_pango = true
} else {
  use_cairo = false
  use_pango = false
}


As a result, use_cairo/use_pango is false on chromeos with GN, whereas before it was 1 in gyp.

This looks like it might be a deliberate change, but there is not a comment so we should double check this.
