* target functionality. The ANGLE broadcast receiver code will apply a "deferlist" at
* the first boot of a newly-flashed device. However, there is a gap in time between
* when applications can start and when the deferlist is applied. For now, assume that
* if ANGLE is the system driver and Settings.Global.ANGLE_DEFERLIST is empty, that the
* deferlist has not yet been applied. In this case, select the Legacy driver.
* otherwise ...
* 3) Use ANGLE if isAngleEnabledByGameMode() returns true; otherwise ...
* 4) The global switch (i.e. use the system driver, whether ANGLE or legacy;
* a.k.a. mAngleIsSystemDriver, which is set by the device’s “ro.hardware.egl” property)
