Now adding an additional fix, allowing y-dimensions not being multiple of 4
(I guess the corresponding bug was there from the beginning but hidden
by sheer luck in memory allocation) and with more optimization the new
code gives for the same test

                    fps = 4310

Which means better than even when the old code could skip the color conversion.

The corrected patch will follow when I figure out how to adjust fate data.
