toggleHighQuality( ) Global Function

change the rendering quality of the PlayerFlash 2; deprecated in
toggleHighQuality()
Description
The toggleHighQuality( ) function switches between High quality and Low quality rendering. When set to High, the Flash Player renders lines with antialiased (smooth) edges. When set to Low, the Flash Player renders lines with aliased (jagged) edges. The toggleHighQuality( ) function does not take any arguments; it simply switches between the two possible settings "High" and "Low". This is problematic because it doesn't explicitly set the quality to a known setting, nor does it allow for more than two different possible quality settings.
As of Flash 5, toggleHighQuality( ) has been deprecated in favor of the global _quality property, which supports Low, AutoLow, Medium, High, AutoHigh, and Best rendering settings.
