+ * SurfaceTexture consumes buffers of graphics data from a BufferQueue,

+ * an application GL render thread as an OpenGL texture.
+ *
+ * When attached to an application GL render thread, a typical usage
+ * pattern is to set up the SurfaceTexture with the
+ * desired options, and call updateTexImage() when a new frame is desired.
+ * If a new frame is available, the texture will be updated. If not,
+ * the previous contents are retained.
+ *
+ * When attached to a HWUI render thread, the TextureView implementation
+ * calls dequeueImage, which either pulls a new SkImage or returns the
+ * last cached SkImage if BufferQueue is empty.
+ * When attached to HWUI render thread, SurfaceTexture is compatible to
+ * both Vulkan and GL drawing pipelines.
