shearY --- shear an image along the y-axis by an arbitrary angle
DESCRIPTION
The shearY operator performs a shear of the input image along the y-axis by
the specified angular amount in the angle parameter. The angle is given in
degrees where positive angles shear the image clockwise. Shearing constrains an
image rotation to a single degree of freedom resulting in a stretching of
the image along the y-axis about the given angle.
