+//
+//  - Every gralloc native buffer with HW read or write requirements will
+//    allocate a host ColorBuffer instance. When gralloc_lock() is called,
+//    the guest will use ColorBuffer::readPixels() to read the current content
+//    of the buffer. When gralloc_unlock() is later called, it will call
+//    ColorBuffer::subUpdate() to send the updated pixels.
+//
+//  - Every guest window EGLSurface is implemented by a host PBuffer
+//    (see WindowSurface.h) that can have a ColorBuffer instance attached to
+//    it (through WindowSurface::attachColorBuffer()). When such an attachment
+//    exists, WindowSurface::flushColorBuffer() will copy the PBuffer's
+//    pixel data into the ColorBuffer. The latter can then be displayed
+//    in the client's UI sub-window with ColorBuffer::post().
+//
+//  - Guest EGLImages are implemented as native gralloc buffers too.
+//    The guest glEGLImageTargetTexture2DOES() implementations will end up
+//    calling ColorBuffer::bindToTexture() to bind the current context's
+//    GL_TEXTURE_2D to the buffer. Similarly, the guest versions of
+//    glEGLImageTargetRenderbufferStorageOES() will end up calling
+//    ColorBuffer::bindToRenderbuffer().
