Fix KisScanlineFill not to tounch point (0,0) on every fill

This patch fixes wery slow application of Magic Wand tool on big images.
The slowdown happened because KisScanlineFill write-accessed every dst
device at position (0,0), when initialized random accessors. It resulted
in dst device extent growing too much, therefore a lot of empty pixels
had to be porcessed at the later stages of contiguous selection.
