    debug: Use cogl_primitive api for paint-volume visualization
    
    Instead of using the cogl_vertex_buffer API this uses the more concise
    cogl_primitive API instead. The aim is to get rid of the
    cogl_vertex_buffer API eventually so we should be trying out the
    replacement API wherever possible.
