[Spice-devel] [PATCH] server/video: do not allow non-streamable drawables be stream candidates

[Yonit Halperin]

Fix a crash caused by a call to __red_is_next_stream_frame made by
red_stream_maintenance, with a drawable that is not a DRAW_COPY one.
Only DRAW_COPY drawables can be streamed, and __red_is_next_stream_frame
refers to red_drawable->u.copy.src_bitmap.
