FRED2 Lollipops don't have a stick

During the code cleanup efforts, I found some functions that suggest that the lollipops, the spheres that are drawn instead of the ship models (if the models are disabled) are supposed to have a stick that visualizes the object's orientation. Users of FRED2 will quickly note that this is not what is happening.

The simplest implementation would help with pitch and bank at the very least, but there should be something else for roll. Could perhaps draw a second stick to act as a "rudder."

The functions of interest are draw_orient_sphere() and draw_orient_sphere2().

Inizia individuando draw_orient_sphere() e draw_orient_sphere2(), quindi esegui FRED2 con i modelli delle navi disabilitati per osservare i lollipops. Traccia il modo in cui viene calcolato l’orientamento attuale della sfera e determina come devono essere rappresentati pitch, bank e roll. Il lavoro è completato quando le sfere sostitutive mostrano visibilmente l’orientamento completo dell’oggetto.
