-/**
- * @fileoverview This page executes various animation behaviors based on URL
- * arguments to test input latency. There are two main modes of
- * operation: webgl and software. Both modes use
- * requestAnimationFrame to drive the update rate. The basic task
- * of the page is to collect mouse input coordinates in the input
- * handler and render with the latest input coordinate in RAF. The
- * latency test will look at the rendering trace data to detect
- * the latest mouse coordinate that affected the frame. For
- * software runs, the pixel at 0,0 on the page must contain the
- * mouse coordinate encoded as a color.
