I know you can change the texture of an image, as mentioned here: http://forum.sparrow-framework.org/topic/change-out-an-image
I also know you can use an SPTween to animate a numerical property.
Is there a straightforward way of animating transition between 2 textures? For instance, I have an image of a square, and another image of the square glowing, and I want to be able to simulate a gradual glow effect by some kind of fade out->fade in effect from the old texture to the new one.
I guess I can use 2 different SPImage objects and animate their alpha property, but I was wondering if there's a way I can do it between 2 textures on the same SPImage object...
