+<!-- Layers used to render the in-call "Audio mode" compound button.
+
+     This is a multi-mode button:
+
+     - If no bluetooth headset is connected, it behaves like a simple
+       "compound button" that switches the speaker on and off.  (This is why
+       the button itself is a ToggleButton instance.)
+
+     - But if a bluetooth headset is connected, this becomes a simple
+       action button (with no concept of a "checked" state) that brings
+       up a popup menu offering you a 3-way choice between earpiece /
+       speaker / bluetooth.
+
+     See InCallTouchUi.updateAudioButton() for the corresponding code. -->

+<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
+
+    <!-- The standard "compound button" background, used to distinguish
+         between the "checked" and "unchecked" states when this button is
+         simply an on/off toggle for the speaker.
+         (In states where the audio button *not* a toggle, we explicitly

+         button, but will instead pop up a menu.  This layer is *not*
+         shown when the audio button is simply an on/off toggle. -->

+         When the audio button is simply an on/off toggle for the speaker,
+         the icon is a "speakerphone" regardless of whether the speaker is
+         active.  (Instead, the "on/off" indication comes from the
+         redphone_btn_compound_background selector.)
+
+         But when the audio button is connected to the 3-way popup menu,
+         we use the button's icon to indicate the current audio mode
+         (i.e. one of { earpiece (or wired headset) , speaker , bluetooth }).
+
+         Here we have separate layers for each possible foreground icon,
+         and in InCallTouchUi.updateAudioButton() we hide them all
+         *except* the one needed for the current state. -->

+              the topmost "Respond by SMS" icon
+            - The negative layout_marginBottom shifts us slightly downward;
+              we're already aligned with the bottom of the screen, but we
+              don't have an icon in the downward direction so the whole
