Paths with images + another object can be picked twice now

[Wumpf]

GPU picking code & image picking code need to talk a little bit more with each other: Images don't show up in GPU picking ids, but another object, on this screenshot a camera, might have the same picking id.
Need to resolve ui for this somehow in a meaningful manner 🤔 (what if the image is picked without a location on it? probably should just show a black zoomed rectangle, or better none at all)
