Background color bug when "next" is enabled.

[Claudio Ficara]

As I was adding shaders onto my project, I discovered a bug.

After adding the required Next content for haxe, by doing:

    <set name="next" />
    <haxedef name="next" />

I noticed the game stayed forever black. Only mouse cursor was visible. Super weird, since Filters demo worked perfectly. After a long process of elimination, I pinpointed the issue.

How to reproduce:

1. Enable Next.
2. Change background color of your state, by either doing:

bgColor = 0x000000;

or

FlxG.cameras.bgColor = 0x000000;

as a workaround you could just simple delete those lines.

As a related issue, I noticed that not enabling next, makes the other effects, such as Invert and color blind modes, available.

Hope this could help someone. Cheers!
