+// ArgGenerators contains argument generators for WebGL functions.
+// The argument generators are used for running random tests against the WebGL
+// functions.
+//
+// ArgGenerators is an object consisting of functionName : argGen -properties.
+//
+// functionName is a WebGL context function name and the argGen is an argument
+// generator object that encapsulates the requirements to run
+// randomly generated tests on the WebGL function.
+//
+// An argGen object has the following methods:
+//   - setup    -- set up state for testing the GL function, returns values
+//                 that need cleanup in teardown. Run once before entering a
+//                 test loop.
+//   - teardown -- do cleanup on setup's return values after testing is complete
+//   - generate -- generate a valid set of random arguments for the GL function
+//   - returnValueCleanup -- do cleanup on value returned by the tested GL function
+//   - cleanup  -- do cleanup on generated arguments from generate
+//   - checkArgValidity -- check if passed args are valid. Has a call signature
+//                         that matches generate's return value. Returns true
+//                         if args are valid, false if not.
+//
+//   Example test loop that demonstrates how the function args and return
+//   values flow together:
+//
+//   var setupArgs = argGen.setup();
+//   for (var i=0; i<numberOfTests; i++) {
+//     var generatedArgs = argGen.generate.apply(argGen, setupArgs);
+//     var validArgs = argGen.checkArgValidity.apply(argGen, generatedArgs);
+//     var rv = call the GL function with generatedArgs;
+//     argGen.returnValueCleanup(rv);
+//     argGen.cleanup.apply(argGen, generatedArgs);
+//   }
+//   argGen.teardown.apply(argGen, setupArgs);
+//
