* Makes a screenshot of the stage in RGBA 8bit data, returns a
* linear buffer with @width * 4 as rowstride.
*
* The alpha data contained in the returned buffer is driver-dependent,
* and not guaranteed to hold any sensible value.
*
* Return value: a pointer to newly allocated memory with the buffer
* or %NULL if the read failed. Use g_free() on the returned data
* to release the resources it has allocated.
