/**
|
|
* Display Modes API
|
|
*
|
|
* A device may implement a list of preset display modes for different
|
|
* viewing intents, such as movies, photos, or extra vibrance. These
|
|
* modes may have multiple components such as gamma correction, white
|
|
* point adjustment, etc, but are activated by a single control point.
|
|
*
|
|
* This API provides support for enumerating and selecting the
|
|
* modes supported by the hardware.
|
|
*
|
|
* A DisplayMode is referenced by it's identifier and carries an
|
|
* associated name (up to the user to translate this value).
