Some figures had a title inside the picture but not in RST file.
As a consequence, some versions of Sphinx are emitting a warning.
Warning, treated as error:
doc/guides/prog_guide/graph_lib.rst:64:
no number is assigned for figure: figure-anatomy-of-a-node
The titles are moved from SVG to RST,
except for graph_mem_layout.svg where in-picture title must be kept.
