Fix DebugOverlay.Text not rendering

[andy013]

I think the native renderer culls objects with uninitialised transform data. Even though DebugOverlay.Text doesn't need a transform, it still has to be set to zero explicitly to get it to render.

[EDIT] Actually, looking at it again, I think it's setting LocalBounds here that's causing the issue:

sbox-public/engine/Sandbox.Engine/Scene/GameObjectSystems/DebugOverlay/DebugOverlaySystem.DrawText.cs

Lines 25 to 29 in 5936916

	Add( duration, new DebugTextSceneObject( Scene.SceneWorld, position, scope, flags )
	{
	RenderLayer = overlay ? SceneRenderLayer.OverlayWithoutDepth : SceneRenderLayer.OverlayWithDepth,
	LocalBounds = BBox.FromPositionAndSize( 0, 256 )
	} );

It uses Transform in it's setter:

sbox-public/engine/Sandbox.Engine/Systems/SceneSystem/SceneObject.cs

Line 202 in 5936916

set => Bounds = value.Transform( Transform );

If the Transform isn't initialised then I think the scale will default to 0 and so nothing will render.

I'm not sure if I'm initialising the Transform in the right place. I guess it's easy enough for you to move now you know what's causing the bug.
