-// Run with --vmodule=latency_tests=1 to print verbose latency info.
-
-// How is latency measured?
-//
-// The test injects mouse moves many times per frame from the browser via
-// RenderWidgetHost. Each input has a unique x coordinate. When the javascript
-// handler receives the input, it stores the coordinate for later use in the
-// requestAnimationFrame callback. In RAF, the test paints using the x
-// coordinate as a color (in software, it sets the color of a table; in webgl,
-// it executes a glClearColor). Trace events emit the color when it is picked up
-// by either UpdateRect for software or gles2_cmd_decoder/glClear for webgl.
-//
-// Each UpdateRect (software) or SwapBuffers (webgl) is considered to be a frame
-// boundary that will be used to measure latency in number of frames. Starting
-// from a frame boundary Y, the test first determines what mouse x coordinate
-// was represented by the color at that frame boundary. Then, the test walks
-// backward through the trace events to find the input event matching that
-// x coordinate. Then, the test find the nearest frame boundary X to the input
-// event (may be before or after). The number of frame boundaries is then
-// counted between X and Y to determine the input latency.
-//
-// By injecting mouse moves many times per frame, we reduce flakiness in the
-// finding of the nearest frame boundary.
-//
-// This test only measures the latency introduced by chrome code -- it does not
-// measure latency introduced by mouse drivers or the GL driver or the OS window
-// manager. The actual latency seen by a user is more than what is reported by
-// this test.
-//
-// Current modes:
-// - Software RAF
-// - WebGL RAF
