"slice at pixel" and "find colliding slice" now ignore parts of slices that are clipped

In particular, this fixes selecting slices in the slice editor by clicking
on them.

However, all other commands like "slice collide point" are unchanged.
Implementing the same for them would require inspecting their ancestors. But
even "slice at pixel" and "find colliding slice" don't check whether any
ancestors of the 'parent' slice clip, they only check its descendents.
