flesh out the mandelbrot iteration loop
...
some bits i missed increased total to:
1939 - 3007 cycles per iteration
probably still buggy, will test later :D

Added two version of 16-bit rounding
...
round16_incdec uses inc and dec
round16_addsub uses adc and sbc
the incdec version is the same when no rounding is needed
but saves about 8 cycles on the rounding cases, for an
average savings of 4.5 cycles for randomly distributed inputs
untested so far
