+/* This is a modified version of 'warped_filter' from warped_motion.c:
+   * Each coefficient is stored in 8 bits instead of 16 bits
+   * The coefficients are rearranged in the column order 0, 2, 4, 6, 1, 3, 5, 7
+
+     This is done in order to avoid overflow: Since the tap with the largest
+     coefficient could be any of taps 2, 3, 4 or 5, we can't use the summation
+     order ((0 + 1) + (4 + 5)) + ((2 + 3) + (6 + 7)) used in the regular
+     convolve functions.
+
+     Instead, we use the summation order
+     ((0 + 2) + (4 + 6)) + ((1 + 3) + (5 + 7)).
+     The rearrangement of coefficients in this table is so that we can get the
+     coefficients into the correct order more quickly.

+Description:
+A feature-complete, generic and customizable resizable
