0.42.4

One Slice fix on top of 0.42.3.

Fixed

• Slice: Point Picking pins no longer float over the "profile replaces heatmap" view. A pin anchored in an axes' own data space kept its old pixel while that view stood in for the data, so a reading of x=0.292, y=0.125, z=1.212 sat at the y=0.125 pixel of an axis that had started reading in the slice's value, pointing at a mesh (or, since 0.42.3, a line) that is not on screen. Annotations anchored the same way did the same. They are now hidden with the series they belong to and restored with them -- on a view change, or on switching Slice off. Pins placed on the profile itself stay, since the thing they point at is what is showing. Hidden, never deleted: Extract still carries them, and they come back untouched. This predates 0.42.3, which only widened it from mesh pins to line and scatter pins as well. A pin selected with an arrow key active is also deselected when it's hidden this way, rather than staying the live target of arrow-key stepping while invisible.
