3DSprite Modifications

[Shannara]

1. The ability to render to a 3DSprite. That way we could create a blank 3dsprite, resize it to needed size, and render from a 2dSprite to a 3dsprite.

2. Rename Zoom to Resize? Zoom would mean make smaller and bigger by same ratio Resize = change width and height (as it is now)
