* Get the properties associated with a display.

|

* The following read-only properties are provided by SDL:
|
||||
*
|
||||
* - `SDL_PROP_DISPLAY_HDR_ENABLED_BOOLEAN`: true if the display has High Dynamic Range enabled
|
||||
* - `SDL_PROP_DISPLAY_SDR_WHITE_LEVEL_FLOAT`: the luminance, in nits, that SDR white is rendered on this display. If this value is not set or is zero, the value 200 is a reasonable default when HDR is enabled.

* \param displayID the instance ID of the display to query
|
||||
* \returns a valid property ID on success or 0 on failure; call

* SDL_GetError() for more information.
