// Read and construct a panel.
+//
+// The panel is specified as a regular property list, and each of the
+// instruments is its own, separate property list (and thus, a separate
+// XML document). The functions in this section read in the files
+// as property lists, then extract properties to set up the panel
+// itself.
+//
+// A panel contains zero or more instruments.
+//
+// An instrument contains one or more layers and zero or more actions.
+//
+// A layer contains zero or more transformations.
+//
+// Some special types of layers also contain other objects, such as
+// chunks of text or other layers.
+//
+// There are currently four types of layers:
+//
+// 1. Textured Layer (type="texture"), the default
+// 2. Text Layer (type="text")
+// 3. Switch Layer (type="switch")
+// 4. Built-in Layer (type="built-in", must also specify class)
+//
+// The only built-in layer so far is the ribbon for the magnetic compass
+// (class="compass-ribbon").
+//
+// There are three types of actions:
+//
+// 1. Adjust (type="adjust"), the default
+// 2. Swap (type="swap")
+// 3. Toggle (type="toggle")
+//
+// There are three types of transformations:
+//
+// 1. X shift (type="x-shift"), the default
+// 2. Y shift (type="y-shift")
+// 3. Rotation (type="rotation")
+//
+// Each of these may be associated with a property, so that a needle
+// will rotate with the airspeed, for example, or may have a fixed
+// floating-point value.
