    padOsd: Use non-deprecated librsvg API to create handle
    
    On one hand, we were using a path instead of an URI on
    rsvg_handle_set_base_uri(). This broke at some point in librsvg
    (presumably for the best, handling paths there sounds non-standard)
    leaving a blank svg (As the base image wouldn't be accessed).
    
    On the other hand, we use this with the deprecated rsvg_handle_write()
    which we should drift away from.
    
    Using rsvg_handle_new_from_stream_sync() neatly solves both. We use
    newer API based on input streams and GFiles, and it internally does
    the right thing, bringing the pad OSD back to life.
