John Cupitt 3dce5951c2 reverse similarity rotation direction convention 
The rest of vips uses +ve-is-clockwise convention, like almost all image

mathematical +ve-is-anticlockwise convention, oops.

John Cupitt 439522a254 add vips_similarity() 
simple wrapper over vips_affine() that lets you give the matrix as scale
+ angle.
