//-------------------------------------------------------------------------
// D3DX_DEFAULT:
// ---------
// A predefined value that could be used for any parameter in D3DX APIs or
// member functions that is an enumerant or a handle. The D3DX
// documentation indicates wherever D3DX_DEFAULT may be used,
// and how it will be interpreted in each situation.
//-------------------------------------------------------------------------
#define D3DX_DEFAULT ULONG_MAX
//-------------------------------------------------------------------------
// D3DX_DEFAULT_FLOAT:
// ------------------
// Similar to D3DX_DEFAULT, but used for floating point parameters.
// The D3DX documentation indicates wherever D3DX_DEFAULT_FLOAT may be used,
// and how it will be interpreted in each situation.
//-------------------------------------------------------------------------
#define D3DX_DEFAULT_FLOAT FLT_MAX
//-------------------------------------------------------------------------
// Hardware Acceleration Level:
// ---------------------------
// These constants represent pre-defined hardware acceleration levels,
// and may be used as a default anywhere a (DWORD) deviceIndex is required.
// Each pre-define indicates a different level of hardware acceleration.
// They are an alternative to using explicit deviceIndices retrieved by
// D3DXGetDeviceDescription().
//
// The only case these pre-defines should be used as device indices is if
// a particular level of acceleration is required, and given more than
// one capable device on the computer, it does not matter which one
// is used.
//
// The method of selection is as follows: If one of the D3DX devices on
// the primary DDraw device supports a requested hardware acceleration
// level, it will be used. Otherwise, the first matching device discovered
// by D3DX will be used.
//
// Of course, it is possible for no match to exist for any of the
// pre-defines on a particular computer. Passing such a value into the
// D3DX apis will simply cause them to fail, reporting that no match
// is available.
//
// D3DX_HWLEVEL_NULL: Null implementation (draws nothing)
// D3DX_HWLEVEL_REFERENCE: Reference implementation (slowest)
// D3DX_HWLEVEL_2D: 2D acceleration only (RGB rasterizer used)
// D3DX_HWLEVEL_RASTER: Rasterization acceleration (likely most useful)
// D3DX_HWLEVEL_TL: Transform and lighting acceleration
// D3DX_DEFAULT: The highest level of acceleration available
// on the primary DDraw device.

// Surface Class:

// These are the various types of 2D-surfaces classified according to their

// bits are part of the same pixel format).

// flag set.
// D3DX_SC_BUMPMAP: All ddpfs which have the DDPF_BUMPLUMINANCE
// or the DDPF_BUMPDUDV flags set.
// D3DX_SC_LUMINANCEMAP: All ddpfs which have the DDPF_BUMPLUMINANCE
// or the DDPF_LUMINANCE flags set.
// D3DX_SC_COLORTEXTURE: All the surfaces that have color information in
