CrossStitchCreator

A fun little tool for converting images to cross stitch patterns.

Todo:

* Increase complexity of patterns.
* Fix Undo feature, especially to the recolouring process.
* Improve ZoomablePictureBox zoom resolution.
* Add scroll/drag to Zoomable picturebox.
* When Zooming in Zoomable picturebox, keep image centred on mouse click.
* Context menu for PatternEditor, eg, to swap patterns.
* Save patterns to *something* for later printing, with info.
* Improve colour editing (like MS Paint)
* Investigate why PatternEditor.UpdateColourMap() is so slow - use progress bar?
