/**
* Animated demonstration on how to use the `clip` shade style to mask-out
* part of an image (or anything else drawn while the shade style is active).
* The clipping uses different fit modes on each row, and different aspect
* ratios in each column.
*
* This example uses a rotating `star`-shaped clipping with 24 sides.
* Other available clipping shapes are `circle`, `rectangle`, `line` and `ellipse`.
*
* Press a mouse button to toggle the `feather` property between 0.0 and 0.5.
