-// Project specific parts of the Win95 DirectX system,
-// largely concerned with the rules for selecting a driver,
-// draw mode, memory mode etc during system initialisation, which
-// cannot readily be decided at a project independent level.
-
-// Must link to C code in main engine system
-
-// Note that TestInitD3DObject is called during InitialiseSystem, immediately
-// after initialisation of the basic DirectDraw object.  It is normally used 
-// to detect the hardware acceleration capabilities of a system, by creating a Direct3D
-// object which is then collapsed again, so that the information can be passed to e.g.
-// menu software to provide recommended options.  The video mode can potentially 
-// be rewritten here, so that a 320x200x8 request mode is interpreted as e.g. 640x480x15
-// if hardware acceleration is detected and it is decided that it will be used.
-
-// Note that the ProcessorType global should be valid at this stage.
-
-
-// TestMemoryAccess is run immediately after TestInitD3DObject in InitialiseSystem,
-// and is used to determine whether the back buffer should be in system or video memory.
-// Note that if you intend to use MMX scan draws the back buffer should be in system memory,
-// if you are running with hardware accelerated draws it MUST be in video memory, and otherwise
-// I would recommend video memory except in extreme circumstances (i.e. very old video cards
-// with very slow VRAM access).  Note that whether or not we will boot on hardware should have been
-// decided by this stage.
-
-// NOTE THAT THE REQUESTSYSTEMMEMORYALWAYS OPTION IS A DEBUGGING FEATURE, SINCE THE WATCOM
-// DEBUGGER CAN ONLY BE USED ON FUNCTIOSN WITHIN DRAWITEMLISTCONTENTS ETC IF THE RENDERING 
-// TARGET IS IN SYSTEM MEMORY AND THE SYSTEM DOES NOT HAVE TO TAKE A WIN16 LOCK TO
-// REACH THE SURFACE.  THIS REQUEST MODE OPTION REPLACES FORCEBUFFERSINTOSYSTEMMEMORY, WHICH
-// WAS AT THE TOP OF DD_FUNC.CPP
-
-// SelectD3DDriverAndDrawMode is the final selection function for hardware acceleration, z buffering
-// etc, run during SetVideoMode from InitialiseDirect3DImmediateMode.  Note that your target video
-// mode must have been selected before you enter this routine.  This routine is separate so that a call
-// to ChangeDisplayModes (in io.c) can be used to change the video mode, driver etc.
-
-// NOTE: USE OF CHANGEDISPLAYMODES MUST BE INTEGRATED WITH USE OF THE CHUNK SYSTEM, SINCE IT WILL
-// REQUIRE A TEXTURE RELOAD AND PROBABLY A SHAPE RELOAD.
-
-// NOTE: IF YOU INTEND TO LET THE USER OVERRIDE VIDEO MODE, DRIVER ETC SETTINGS FROM MENUS RUN
-// (UNAVOIDABLY, I SUSPECT) AFTER INITIALISESYSTEM, YOU MUST CALL SETVIDEOMODE BEFORE THE MENUS
-// IF YOU WANT THEM TO BE DISPLAYED USING ENGINE (DIRECTX) FUNCTIONS AND THEN CALL CHANGEDISPLAYMODES
-// TO CHANGE THE MODES TO THE FINAL ONES.  DO NOT CALL SETVIDEOMODE TWICE DURING A SINGLE PROGRAM RUN.
-// CHANGEDISPLAYMODES WILL CALL YOUR VERSION OF SELECTD3DDRIVERANDDRAWMODE FOR YOU, BUT TESTMEMORYACCESS
-// AND TESTINITD3DOBJECT WILL NOT BE CALLED AGAIN.  IF YOU WANT TO RESELECT THE MEMORY MODE OR RETEST
-// HARDWARE ACCELERATION CAPABILITIES, YOU MUST DO IT YOURSELF IN THE MENUS SYSTEM.
-
-// NOTE: TO CHANGE PALETTE IN A PALETTISED MODE, CALL CHANGEPALETTE IN IO.C, NOT CHANGEDISPLAYMODES.
