ExceptionCaster::filterTrace() is deprecated and replaced by a more flexible backtrace processing that allows one to register casters for amending/changing dumped backtraces. This is especially useful for dumping source map information/excerpts (like e.g. twig template source).
Here is a comparison generated with this code snippet (see also the expected output in testThrowingCaster):
```php
namespace Symfony\Component\VarDumper\Caster;
require 'vendor/autoload.php';
function bar()
{
return foo();
}
function foo()
{
dump(new \Exception('baz'));
}
bar('aaaaarg');
```
