[Inkscape-devel] A possible error in livarot\MyMath.h

I am new to InkScape, but from what I remember from math lessons the dot product and the cross product as defined in the file have been confused.

Dot is defined to be x*x + y*y, but in this file the author defined cross to be x*x + y*y. And also cross should be x*y - y*x, but the author defined Dot to be x*y - y*x.

Thanks, Alex.
