/*
 * D3DX_FILTER flags:
 * ------------------
 *
 * A valid filter must contain one of these values:
 *
 *  D3DX_FILTER_NONE
 *      No scaling or filtering will take place.  Pixels outside the bounds
 *      of the source image are assumed to be transparent black.
 *  D3DX_FILTER_POINT
 *      Each destination pixel is computed by sampling the nearest pixel
 *      from the source image.
 *  D3DX_FILTER_LINEAR
 *      Each destination pixel is computed by linearly interpolating between
 *      the nearest pixels in the source image.  This filter works best
 *      when the scale on each axis is less than 2.
 *  D3DX_FILTER_TRIANGLE
 *      Every pixel in the source image contributes equally to the
 *      destination image.  This is the slowest of all the filters.
 *  D3DX_FILTER_BOX
 *      Each pixel is computed by averaging a 2x2(x2) box pixels from
 *      the source image. Only works when the dimensions of the
 *      destination are half those of the source. (as with mip maps)
 *
 * And can be OR'd with any of these optional flags:
 *
 *  D3DX_FILTER_MIRROR_U
 *      Indicates that pixels off the edge of the texture on the U-axis
 *      should be mirrored, not wraped.
 *  D3DX_FILTER_MIRROR_V
 *      Indicates that pixels off the edge of the texture on the V-axis
 *      should be mirrored, not wraped.
 *  D3DX_FILTER_MIRROR_W
 *      Indicates that pixels off the edge of the texture on the W-axis
 *      should be mirrored, not wraped.
 *  D3DX_FILTER_MIRROR
 *      Same as specifying D3DX_FILTER_MIRROR_U | D3DX_FILTER_MIRROR_V |
 *      D3DX_FILTER_MIRROR_V
 *  D3DX_FILTER_DITHER
 *      Dithers the resulting image.

 *  D3DX_NORMALMAP_COMPUTE_OCCLUSION
 *      Compute the per pixel Occlusion term and encodes it into the alpha.
 *      An Alpha of 1 means that the pixel is not obscured in anyway, and
 *      an alpha of 0 would mean that the pixel is completly obscured.
