Sketches now have a reflect method. Added animation tests for reflection. Polygons now have a points property that is used for translation and reflection.
Reflection now works for textbits. Added a width property to textbits to let that work properly. Might need tweaking.
Sketch textbits now have slightly smaller font (10px for letters, 6px for subcripts). Text is now anchored in the middle to make reflection easier. Sketch and animation tests have been updated as well.
Reflections now have a duration, which can create fake-3d effects.

Note: Circles and rectangles cannot "flip" the way polygons and lines can, because they are not represented as a series of points.
Changed test 8 sketch.
