UriClip
Description:
Creates a new UriClip for the provided uri.
Note:
**WARNING**: This function might 'discover` uri **synchrounously**, it is an IO and processing intensive task that you
probably don't want to run in an application mainloop. Have a look at
Asset.request_async to see how to make
that operation happen **asynchronously**.
Parameters:
| uri |
the URI the source should control |
Returns:
|
The newly created UriClip, or null if there was an error. |
