Allows an application to use SurfaceFlinger's low level features

 Allows an application to use SurfaceFlinger's low level features -->
<permission android:name="android.permission.ACCESS_SURFACE_FLINGER"
android:label="@string/permlab_accessSurfaceFlinger"
android:description="@string/permdesc_accessSurfaceFlinger"
android:protectionLevel="signature" />

Going from 1.1 to 1.5 the SurfaceFlinger protectionLevel has been
bumped to signature.  I suppose this was to stop people using the
isurface directly to render graphics and to ensure the android
development process remained as uniform as possible?  I can see the
logic here, though I would be better if this was left at dangerous
until the proper NDK was released so developers can do some
prototyping.  Then again, if I want to do prototyping I can always
edit the file myself...

Thanks

Chris

를 사용하면 surfaceflinger의 low level 기능을 사용 할 수 있다고 되어 있는데 도대체 low level 기능은 뭘까?
