If you need an exemption to this rule, contact Hixie or stuartmorgan on the #hackers channel in Chat (don't just cc them here, they won't see it! Use Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

The macOS desktop driver doesn't support ES profiles, and `glClearDepthf` + `glDepthRangef` are throwing `GL_INVALID_OPERATION` and doing nothing. Noticed this while updating impeller-cmake past @matanlurey's recent changes to make `GL_INVALID_OPERATION` fatal. Impeller-cmake-example uses a depth buffer, whereas Impeller's 2D renderer currently does not. Added a follow-up bug to make these calls work on macOS desktop: flutter/flutter#136322. Both Impeller Scene and the impeller-cmake-example currently just rely on the default state for clearing depth.
