+// DeferGlobalInitializers is an AST traverser that moves global initializers into a separate
+// function that is called in the beginning of main(). This enables initialization of globals with
+// uniforms or non-constant globals, as allowed by the WebGL spec. Some initializers referencing
+// non-constants may need to be unfolded into if statements in HLSL - this kind of steps should be
+// done after DeferGlobalInitializers is run. Note that it's important that the function definition
+// is at the end of the shader, as some globals may be declared after main().
+//
+// It can also initialize all uninitialized globals.
