// 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.
