+    The cockpit displays work slightly different.  There's two of them, and you select them by using the
+    'monitor_left' and 'monitor_right' classes, illustrated below.  The backing textures appear to be
+    pixel-addressable at 512x512.  When not in free-look mode, the bottom-visible pixel is 294.  The remainder
+    can be seen only in free-look.
