Hi Michael & Krita developers,

I did gimp-deskew; great job porting it to Krita :)

The actual skew detection algorithm actually operates on a
bit-packed B&W image.  The conversion route is quite simplistic.
In the comments I wrote "convert RGB/grayscale to B&W" because
GIMP only supports those, but it should be easy to get it to work
with other colorspaces.
