Customizability of tooltip

[stargazing-dino]

We should allow for more customizations. A good starting point would be to try to implement some of these:

• Frosted look
• Outline of tooltip
• Better Shadow properties (List?)

Edit

I might want to consider whether the tooltip should be the space around the tail as well and if the tail should just be gotten from a clipper. That would make things like frosted glass a lot easier to implement. I think it'd complicate gestures though. Just a guess.

I'm considering making the entire tooltip just a custom clip path. This would allow users to have their tail be the same as their inner content and users would just pad their content tailTip length away from the edge:

so replace content with:

builder: (margin) {
  return Material(
    // Tooltip tail will share this color
    color: Colors.grey.shade800,
    child: Container(
      margin: margin,
      child: const SizedBox(
        width: 100.0,
        height: 100.0,
      ),
    ),
  );
},

My concern is that that looks weird. I've never seen anyone else pass through margin.

What about

content: const SizedBox(
  width: 100.0,
  height: 100.0,
),
background: Material(
  color: Colors.grey.shade800,
),

and then they are placed together via a stack? The content is offset by the offsetAndTailLength and the background is clipped by the tail clipper and borderRadius argument.
