/** Function oyDeviceGetProfile
* @brief order a device profile
*
* This function is designed to satisfy most users as it tries to deliver

* Following code can almost allways expect some profile to go with.
* It tries hard to get a current profile or set the system up and retry or
* get at least one basic profile.
*
* For a basic and thus weaker call to the device use
* oyDeviceAskProfile2() instead.
*
* @param device the device
* @param options
* - options passed to the backend
* - "///icc_profile_flags" with a int
* containing ::OY_ICC_VERSION_2 or
* ::OY_ICC_VERSION_4
* @param profile the device's ICC profile
