Merge and remove WARPEDPIXEL_FILTER_BITS 

This macro is same as FILTER_BITS and the two can be safely merged.

This allows the derivation of the appropriate bit widths and offsets for
the various intermediate values: If
F := WARPEDPIXEL_FILTER_BITS = 7 (or else the above ranges need adjusting)
F := FILTER_BITS = 7 (or else the above ranges need adjusting)
So a *single* filter stage maps a k-bit input to a (k + F + 1)-bit
intermediate value.
