pattern: Add observer hooks

In order for custom context to automatically track when a pattern is
modify after being set on the context (and before it is used in an
operator), we need for there to be a callback when the pattern is
modified.

-/*
- * A mesh patch is a tensor-product patch (bicubic Bezier surface
- * patch). It has 16 control points. Each set of 4 points along the
- * sides of the 4x4 grid of control points is a Bezier curve that
- * defines one side of the patch. A color is assigned to each
- * corner. The inner 4 points provide additional control over the
- * shape and the color mapping.
- *
- * Cairo uses the same convention as the PDF Reference for numbering
- * the points and side of the patch.
