Problem
1. Determine a sequence of basic transformations that are equivalent to the x-direction shearing matrix (5-53).
2. Determine a sequence of basic transformations that are equivalent to the y-direction shearing matrix (5-57)
3. Set up a shearing procedure to display italic characters, given a vector font definition That is, all character shapes in this font are defined with straight-line segments, and italic characters are formed with shearing transformations. Determine art appropriate value for the shear parameter by comparing italics and plain text in some available . Define a simple vector font for input to your routine.
