      Use the sx/sy sliders to adjust the x/y scale of our unit circle,
      and use the shx/shy sliders to adjust the x/y shear components. The
      code will generate three points on the circle (aqually spaced
      angularly), transform those using the slider parameters, then 
      construct a covariance matrix, calculate the eigenvalues and
      eigenvectors, and use those to determine what the ellipse looks
      like that we get when we transform the entire circle according

Writing Type2 sin(x) and cos(x) functions

If we want to make a font in which the glyphs are turned some random amount, we'll need to make sure we have a rotate function available. Normally, this is something you do with a rotation matrix, but that rotation matrix depends on trigonometric functions, and Type2 charstring instructions don't come with a trig. library, so ... we need to write our own!

In fact, let's use Bhaskara I's method of "sort of kind of" approximating a sine wave -or rather half of one- by using a relatively simple expression:

                 4x(π-x)
sin(x) = 4 * ----------------
              5π^2 - 4x(π-x)
