-Avoiding the branch bubble in the AREA_MULT could be done with either:
-
-area = (w * h + 1) >> 1;
-area |= ((area - 1) & 0x80000000);
-
-or
-        #define AREA_MULT(w,h) ((((w)*(h) + 1) >> 1) | ((w)&(h)&0x10000) << 15)
-
-depending on your preference, the first takes one less operation but
-can't be expressed as a macro; the second takes a large constant which may
-require an additional instruction on some processors.  The differences
-will be swamped by the cost of the multiply.
