+ * FUNCTION
+ * mlib_ImageAffineEdgeZero - implementation of MLIB_EDGE_DST_FILL_ZERO
+ * edge condition
+ * mlib_ImageAffineEdgeNearest - implementation of MLIB_EDGE_OP_NEAREST
+ * edge condition
+ * void mlib_ImageAffineEdgeExtend_BL - implementation of MLIB_EDGE_SRC_EXTEND
+ * edge condition for MLIB_BILINEAR filter
+ * void mlib_ImageAffineEdgeExtend_BC - implementation of MLIB_EDGE_SRC_EXTEND
+ * edge condition for MLIB_BICUBIC filter
+ * void mlib_ImageAffineEdgeExtend_BC2 - implementation of MLIB_EDGE_SRC_EXTEND
+ * edge condition for MLIB_BICUBIC2 filter
+ *
+ * DESCRIPTION
+ * mlib_ImageAffineEdgeZero:
+ * This function fills the edge pixels (i.e. thouse one which can not
+ * be interpolated with given resampling filter because their prototypes
+ * in the source image lie too close to the border) in the destination
+ * image with zeroes.
+ *
+ * mlib_ImageAffineEdgeNearest:
+ * This function fills the edge pixels (i.e. thouse one which can not
+ * be interpolated with given resampling filter because their prototypes
+ * in the source image lie too close to the border) in the destination
+ * image according to the nearest neighbour interpolation.
+ *
+ * mlib_ImageAffineEdgeExtend_BL:
+ * This function fills the edge pixels (i.e. thouse one which can not
+ * be interpolated with given resampling filter because their prototypes
+ * in the source image lie too close to the border) in the destination
+ * image according to the bilinear interpolation with border pixels extend
+ * of source image.
+ *
+ * mlib_ImageAffineEdgeExtend_BC:
+ * This function fills the edge pixels (i.e. thouse one which can not
+ * be interpolated with given resampling filter because their prototypes
+ * in the source image lie too close to the border) in the destination
+ * image according to the bicubic interpolation with border pixels extend
+ * of source image.
+ *
+ * mlib_ImageAffineEdgeExtend_BC2:
+ * This function fills the edge pixels (i.e. thouse one which can not
+ * be interpolated with given resampling filter because their prototypes
+ * in the source image lie too close to the border) in the destination
+ * image according to the bicubic2 interpolation with border pixels extend
+ * of source image.
