*
*  Module Name    vpmv7.h
*  Project        Rage128 DAL GDO
*  Device         Rage
*
*  Description    header file for Display Abstraction Layer
*    the follow file defines the VIDEO_PARAMETER structure and calling parameters
*    change to the ChangeDisplaySettingEx() Win32 API. 
*
*    The audience for this file are Win32 developers who want to call
*    ChangeDisplaySettingEx with the CDS_VIDEOPARAMETERS flag set, and
*    display driver developers who want to implement the VIDEO_PARAMETERS 
*    escape in their Control() function
*    there is a problem in DAL supporting DWORD / WORD / BYTE so these are
*    temporarly defined to prevent this header from being re-written 
*    specifically for DAL  25/11/98 [GG]
