* HWC_FRAMEBUFFER or HWC_OVERLAY. In the former case, the composition for
* this layer is handled by SurfaceFlinger with OpenGL ES, in the later
* case, the HWC will have to handle this layer's composition.
*
* (*prepare)() is called with HWC_GEOMETRY_CHANGED to indicate that the
* list's geometry has changed, that is, when more than just the buffer's
* handles have been updated. Typically this happens (but is not limited to)
* when a window is added, removed, resized or moved.
*
* a NULL list parameter or a numHwLayers of zero indicates that the
* entire composition will be handled by SurfaceFlinger with OpenGL ES.

* the actual eglSwapBuffers().
*
* The list parameter is guaranteed to be the same as the one returned
* from the last call to (*prepare)().
*
* When this call returns the caller assumes that:
*
* - the display will be updated in the near future with the content
* of the work list, without artifacts during the transition from the
* previous frame.
*
* - all objects are available for immediate access or destruction, in
* particular, hwc_region_t::rects data and hwc_layer_t::layer's buffer.
* Note that this means that immediately accessing (potentially from a
* different process) a buffer used in this call will not result in
* screen corruption, the driver must apply proper synchronization or
* scheduling (eg: block the caller, such as gralloc_module_t::lock(),
* OpenGL ES, Camera, Codecs, etc..., or schedule the caller's work
* after the buffer is freed from the actual composition).
*
* a NULL list parameter or a numHwLayers of zero indicates that the
* entire composition has been handled by SurfaceFlinger with OpenGL ES.
* In this case, (*set)() behaves just like eglSwapBuffers().
*
* dpy, sur, and list are set to NULL to indicate that the screen is
* turning off. This happens WITHOUT prepare() being called first.
* This is a good time to free h/w resources and/or power
* the relevant h/w blocks down.
*
* IMPORTANT NOTE: there is an implicit layer containing opaque black
* pixels behind all the layers in the list.
* It is the responsibility of the hwcomposer module to make
* sure black pixels are output (or blended from).
*
* returns: 0 on success. An negative error code on error:
* HWC_EGL_ERROR: eglGetError() will provide the proper error code
* Another code for non EGL errors.
