Code review comment for lp://qastaging/~mir-team/mir/animated-cursors

needs info:
130 + * Create a new buffer stream unattached to a surface.

I guess, outside of cursors, is this a universal concept? I guess I'm just a bit leery of saying "this is a surface, with a bufferstream" and "this is a bufferstream", because it seems difficult to understand, if you're only looking at the API.

needs fixings:
216 + * If the configuration successfully applied buffers from the stream will be used
needs a verb
220 + * \param [in] hotspot_y The y-coordinate displacement within the image to place on the cursor.
