/*
 * 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.
