+// RewriteStructSamplers: Extract structs from samplers.
+//
+// This traverser is designed to strip out samplers from structs. It moves them into separate
+// uniform sampler declarations. This allows the struct to be stored in the default uniform block.
+// This transformation requires MonomorphizeUnsupportedFunctions to have been run so it
+// wouldn't need to deal with functions that are passed such structs.
+//
+// For example:
+//   struct S { sampler2D samp; int i; };
+//   uniform S uni;
+// Is rewritten as:
+//   struct S { int i; };
+//   uniform S uni;
+//   uniform sampler2D uni_i;
