-/**
- * The TiledPage represents a map of BaseTiles covering the viewport. Each
- * GLWebViewState contains two TiledPages, one to display the page at the
- * current scale factor, and another in the background that we use to paint the
- * page at a different scale factor.  For instance, when we zoom using one
- * TiledPage its tiles are scaled in hardware and therefore are subject to a
- * loss of quality. To address this when the user finishes zooming we paint the
- * background TilePage at the new scale factor.  When the background TilePage is
- * ready, we swap it with the currently displaying TiledPage.
