/* For future doc:
https://github.com/codac-team/codac/pull/126#discussion_r1829030491
Pour les véhicules (draw_tank et draw_AUV) le header par défaut du begin_path n'est pas suffisant.
J'ai donc ajouté cette fonction qui fait le même travail que le begin_path, avec en plus le champ
"matrix" complété.
Ce champ contient 6 valeurs : les 4 premières sont la matrice de transformation 2D, rotation et
dilatation, "par colonne" (i.e. m11, m21, m12, m22) et les 2 autres valeurs sont la translation.
Le tout permet de scale le véhicule, l'orienter et le déplacer au bon endroit.
Cette fonction écrit dans le xml quelque chose dans le style :
<path layer="alpha"
stroke="codac_color_000000"
fill="codac_color_ffd32a"
opacity="100%"
stroke-opacity="100%"
pen="heavier"
matrix="0.00948009 11.9048 -11.9047 0.00948009 166.667 166.667">
