+/* This DisplaySurface implementation supports virtual displays, where GLES
+ * and/or HWC compose into a buffer that is then passed to an arbitrary
+ * consumer (the sink) running in another process.
+ *
+ * The simplest case is when the virtual display will never use the h/w
+ * composer -- either the h/w composer doesn't support writing to buffers, or
+ * there are more virtual displays than it supports simultaneously. In this
+ * case, the GLES driver works directly with the output buffer queue, and
+ * calls to the VirtualDisplay from SurfaceFlinger and DisplayHardware do
+ * nothing.
+ *
+ * If h/w composer might be used, then each frame will fall into one of three
+ * configurations: GLES-only, HWC-only, and MIXED composition. In all of these,
+ * we must provide a FB target buffer and output buffer for the HWC set() call.
+ *
+ * In GLES-only composition, the GLES driver is given a buffer from the sink to
+ * render into. When the GLES driver queues the buffer to the
+ * VirtualDisplaySurface, the VirtualDisplaySurface holds onto it instead of
+ * immediately queueing it to the sink. The buffer is used as both the FB
+ * target and output buffer for HWC, though on these frames the HWC doesn't
+ * do any work for this display and doesn't write to the output buffer. After
+ * composition is complete, the buffer is queued to the sink.
+ *
+ * In HWC-only composition, the VirtualDisplaySurface dequeues a buffer from
+ * the sink and passes it to HWC as both the FB target buffer and output
+ * buffer. The HWC doesn't need to read from the FB target buffer, but does
+ * write to the output buffer. After composition is complete, the buffer is
+ * queued to the sink.
+ *
+ * On MIXED frames, things become more complicated, since some h/w composer
+ * implementations can't read from and write to the same buffer. This class has
+ * an internal BufferQueue that it uses as a scratch buffer pool. The GLES
+ * driver is given a scratch buffer to render into. When it finishes rendering,
+ * the buffer is queued and then immediately acquired by the
+ * VirtualDisplaySurface. The scratch buffer is then used as the FB target
+ * buffer for HWC, and a separate buffer is dequeued from the sink and used as
+ * the HWC output buffer. When HWC composition is complete, the scratch buffer
+ * is released and the output buffer is queued to the sink.
