CBS_OWNERDRAWFIXED only hands over the item area, so while the list rows
came out green on black, the closed box kept the system's frame and drop
arrow - a white/grey Windows control sitting in the middle of a black panel.
The closed box is painted here now: black field, dim green border, bright
green text, and a plain green triangle instead of a themed button. The
control keeps doing everything else, including dropping its list, so this is
a subclass over WM_PAINT rather than a reimplementation.
Still system-drawn: the scrollbar inside a dropped list, which only appears
on the two lists longer than twelve rows - vehicle and track.
