[Gum] "Clips Children" doesn't work properly with rotation

[Arcnor]

1. Create a Parent and Text object, make Text child of Parent
2. Add a lot of text to Text
3. Enable "Clips Children" on Parent
4. Rotate Parent

Clipping will ignore the rotation so it will look broken.

Do you need clipping to respect rotation at 90 degree increments, or arbitrary angles? If 90i can implement a very quick fix. If any angle, it will take a little longer

I'm animating something (or trying to :D), so angles will be random. Better to wait until the proper solution is in place, for sure :).

I started on this by working on needing render targets to do rendering. This will allow an object to render itself to a render target and then to render that render target with rotation.

This is currently being worked on in Renderer.cs in this block of code:

if (renderable.ClipsChildren)
{
    var userRenderTarget = false;

    if(userRenderTarget)
    {
        var renderTarget = new RenderTarget2D(GraphicsDevice, 64, 64);
        renderState.RenderTarget = renderTarget;
        GraphicsDevice.SetRenderTarget(renderTarget);
        GraphicsDevice.Clear(Color.Transparent);
        shouldResetStates = true;
    }

This work is in RenderTargetObjects branch.
