Support more affine expression forms in im.point(), deprecate Image.coerce_e #6254

  1. Support more affine expression forms in Image.point 

    In modes I and F, Image.point only supported affine expressions of the
forms (lambda x:) x * a, x + a, and x * a + b. Expressions like 1 - x
had to be written x * -1 + 1.

This rewrite, though still limited to affine transformations, supports
far more expression forms, including 1 - x, (2 * x + 1) / 3, etc.
