edge blending options and/or blur the edges about haze

[chrisbanes]

This sounds like a duplicate of #132?

Also, attaching screenshots for visual issues is probably a good idea. Trying to describe with words is obviously not going to work.

ok, so I added 2 pictures,

1. the first one is a regular implementation of haze-

as you can see in the above picture, the blur is at the same level from the center to the edges, which makes it very noticeable. and for some scenarios, we need the blur to integrate into the view

2. in this picture, I added some hacky, bad implementation of haze using a for loop over shapes to make the blurred edges less noticeable and somewhat leveling from center to the edge -

It could be very useful if we could make the blur spot from the center and get less and less noticeable to the edges.

I'm afraid that the APIs we have available don't easily support radial blurring.

There might be some clever ways to implement this via a runtime shader, but it would be difficult to do that across all platforms.

I think this is basically infeasible. If anyone thinks of a good to handle this, PRs welcome!
