I plan to use this to implement similar logic in SliverPadding. To make this easier to test I extended the paints matcher to accept a function that takes a canvas. While I was at it I also made it accept a Finder, it'll go and find the render object for you. Also added support for paints..path and fixed some grammar in the error messages. Also improved the docs for debugPaint*.
