Shearing slides one edge of an image along the X or Y axis, creating
a parallelogram. An X direction shear slides an edge along the X axis,
while a Y direction shear slides an edge along the Y axis. The amount
of the shear is controlled by a shear angle. For X direction shears,
xShearAngle is measured relative to the Y axis, and similarly, for Y
direction shears yShearAngle is measured relative to the X axis.
Empty triangles left over from shearing the image are filled with
the background color.
