**** directories *****

d3dif - D3D interface.  This contains the sources for the interface
between the D3D runtime and the rasterizers.

bin - Rasterizer-specific tools.  This holds the m4.exe needed to build
the numerous m4-ized C++ and asm source files.

inc - Rasterizer-private header files.

refrast - Reference rasterizer sources.  This is the core of the reference
rasterizer, holding all sources which are made public with the DDK.  The
reference rasterizer core is fully independent of any D3D or DDraw
internals, and is connected to the runtime via refif.cpp in the d3dif
directory.  The file inc\refrast.h is also part of the reference
rasterizer package.

setup - Primitive setup.  Contains C++ and x86 assembly for primitive
setup and edge walking.

spaninit - Span iterator management code.

cspan - C span iterators.  These are the span iterators used on non-MMX
(including alpha) machines.

cmmxspan, mmxemul - C span iterators which closely model the MMX versions
for development and debug purposes.  The mmxemul is a library which
emulates the MMX arithmetic functions.  This is a full set of span
iterators which exactly matches the set in mmxspan, and are used when the
???  device GUID is passed to device create.  These are for internal
debug/test only and are not used in the product (the associated GUID is
not in the public d3d.h).

mmxspan - MMX assembly span iterators.

mlspan - Monolithic span iterators.

rampmat - Ramp rasterizer material processing.  See rampmat/ramp.txt for
further explanation (the horror...).

rampspan - Ramp rasterizer span iterators.  C and x86 assembly.

d3drast - This directory is used only to build the d3drast.dll, which is a
library which contains only the rasterizers (accessed via the HAL provider
interface).  This is a test-only library and is not part of the product
build.

    CONSOLE APPLICATION : Rast Project Overview
========================================================================

AppWizard has created this Rast application for you.  
This file contains a summary of what you will find in each of the files that
make up your Rast application.
Rast.vcproj
    This is the main project file for VC++ projects generated using an Application Wizard. 
    It contains information about the version of Visual C++ that generated the file, and 
    information about the platforms, configurations, and project features selected with the
    Application Wizard.

Rast.cpp
    This is the main application source file.

/////////////////////////////////////////////////////////////////////////////
Other standard files:

StdAfx.h, StdAfx.cpp
    These files are used to build a precompiled header (PCH) file
    named Rast.pch and a precompiled types file named StdAfx.obj.

Resource.h
    This is the standard header file, which defines new resource IDs.
    Microsoft Visual C++ reads and updates this file.
/////////////////////////////////////////////////////////////////////////////
Other notes:

AppWizard uses "TODO:" comments to indicate parts of the source code you
should add to or customize.
