Both fixes the bug (as in: the referenced test SVG with shearing now renders 
correctly) as looks mathematically correct (one radian is equal to 180/π 
degrees, so
 y radian = x degree <=> (substitute radian with degree)
 y 180/π degree = x degree <=> (multiply by 1/degree)
 y 180/π = x <=> (multiply with π/180)
 y = π/180 x)

Cheers
