 * \brief	interface of d3d9 render module
 *
 * \date	Created 12/14/2010
 *
 * \description : 1. Rendering in Vista and upper : D3D9Ex method, support host memory / shared surface input 
 *                2. Rendering in XP : D3D9 method w/o device lost handling, support host memory input  
 *                3. File Dump : support host memory / shared surface input
