// D3DXCreateTextureFromFile/Resource:
// -----------------------------------
// Create a texture object from a file or resource.
//
// Parameters:
//
//  pDevice
//      The D3D device with which the texture is going to be used.
//  pSrcFile
//      File name.
//  hSrcModule
//      Module handle. if NULL, current module will be used.
//  pSrcResource
//      Resource name in module
//  pvSrcData
//      Pointer to file in memory.
//  SrcDataSize
//      Size in bytes of file in memory.
//  Width, Height, Depth, Size
//      Size in pixels; if zero or D3DX_DEFAULT, the size will be taken
//      from the file.
//  MipLevels
//      Number of mip levels;  if zero or D3DX_DEFAULT, a complete mipmap
//      chain will be created.
//  Usage
//      Texture usage flags
//  Format
//      Desired pixel format.  If D3DFMT_UNKNOWN, the format will be
//      taken from the file.
//  Pool
//      Memory pool to be used to create texture
//  Filter
//      D3DX_FILTER flags controlling how the image is filtered.
//      Or D3DX_DEFAULT for D3DX_FILTER_TRIANGLE.
//  MipFilter
//      D3DX_FILTER flags controlling how each miplevel is filtered.
//      Or D3DX_DEFAULT for D3DX_FILTER_BOX,
//  ColorKey
//      Color to replace with transparent black, or 0 to disable colorkey.
//      This is always a 32-bit ARGB color, independent of the source image
//      format.  Alpha is significant, and should usually be set to FF for 
//      opaque colorkeys.  (ex. Opaque black == 0xff000000)
//  pSrcInfo
//      Pointer to a D3DXIMAGE_INFO structure to be filled in with the 
//      description of the data in the source image file, or NULL.
//  pPalette
//      256 color palette to be filled in, or NULL
//  ppTexture, ppCubeTexture, ppVolumeTexture
//      The texture object that will be created
//
