20 * TODO(epoger): Make constant strings consistent instead of mixing hypenated an d camel-caps.

21 *

22 * TODO(epoger): Similar constants are already maintained in 2 other places:

23 * gm/gm_json.py and gm/gm_expectations.cpp. We shouldn't add yet a third place.

24 * Figure out a way to share the definitions instead.

25 *

26 * Note that, as of https://codereview.chromium.org/226293002 , the JSON

27 * schema used here has started to differ from the one in gm_expectations.cpp .

28 * TODO(epoger): Consider getting GM and render_pictures to use the same JSON

29 * output module.
