position Rectangle on the screen to draw the texture within.
image Texture to display.
scaleMode How to scale the image when the aspect ratio of it doesn't fit the aspect ratio to be drawn within.
imageAspect Aspect ratio to use for the source image. If 0 (the default), the aspect ratio from the image is used.
