//

// These are drop-in replacements for FastLED.show() and FastLED.delay()
// In order to use these, you have to actually replace your calls to
// FastLED.show() and FastLED.delay() with these two functions.
//
// Example:
//     // was: FastLED.show();
//     // now is:
//     show_at_max_brightness_for_power();
//

// Power Control internal helper functions
//
// calculate_unscaled_power_mW tells you how many milliwatts the current
//   LED data would draw at brightness = 255.
//
// calculate_max_brightness_for_power_mW tells you the highest brightness
//   level you can use and still stay under the specified power budget.  It
//   takes a 'target brightness' which is the brightness you'd ideally like
//   to use.  The result from this function will be no higher than the
//   target_brightess you supply, but may be lower.
