Optimized out fill="#000" despite <g> shadowing

[espadrine]

Reproducible with the following code.

var SVGO = require('svgo');
var svgo = new SVGO();
svgo.optimize('<g fill="#fff"><text y="20" fill="#000">Foo!</text></g>', function(res) { console.log(res); });

Output:

<g fill="#fff"><text y="20">Foo!</text></g>

Desired output:

<g fill="#fff"><text y="20" fill="#000">Foo!</text></g>

In that case, the fill shadows the fill performed by the <g>, which has the effect of making the text invisible, when it should be black.

(Obviously, this is a contrived example given as the reduced test-case of a larger image.)

@silentroach, is this was fixed in #165/#166 as well? if so, it will be available in the next patch version.

[espadrine]

@deepsweet That's great news! (The above test case is on the latest v0.4.3.)

Maybe it would nevertheless make sense to add a unit test for the above request

[silentroach]

@deepsweet yep, didn't see this issue
@staabm added in #165

[deepsweet]

ok :) v0.4.4 is coming soon.
