This is a follow-up to the missing pixels issue I mentioned in comment #314

It seems to me that all lines are actually drawn one pixel too short. Usually
this is not noticeable since you explicitly draw the perimeter but sometimes
the problem shows. DIBDRV_Polygon calls physDev->brushHLine to do the drawing
and the implementation of HLine draws the pixels from "start" to "end-1".
Should HLine be modified to also draw the "end" pixel? Or should Polygon be
modified to request one more pixel to be drawn?
