Add zoom tool, zoom menu items #21

Open cmeyer opened 7 years ago

cmeyer commented 7 years ago

From Tracy: For zooming in an out, we use "+", but then you are always zooming about the center. If we use the track wheel on the mouse, we could zoom about the cursor, and then you could zoom in on a particular feature.

From Niklas: The best tracking devices, track balls often come without a scroll wheel, so making + and - move around the cursor would be better. There is a usability issue in Swift in that it doesn't actually know where the cursor is, but it should.

### Tasks
- [ ] https://github.com/nion-software/nionswift/issues/1137
- [ ] Add zoom menu items (zoom around mouse if cursor in panel, otherwise center)
- [ ] Add zoom by scroll wheel / track pad (zoom around mouse position)

Maybe both ideas should be implemented? But I definitely think Tracy's idea should, because this is what the mouse wheel does in most applications. Right now it moves images up/down in Swift, which is not very useful. A nice side effect of zooming around the cursor is that you can use that to move the image around. Moving images is often a bit awkward in many programs, so using "zoom around the cursor" is a decent workaround.

Niklas' idea might be useful, too, but I 'm afraid that this can be confusing for users. Maybe we should just get trackballs with mouse wheels?

I've looked, none of the good index finger trackballs come with scroll wheels, they only have the little minibuttons.

Actually I think having a scroll wheel would be nice also for general use of the user pc.

PR for this currently is: https://github.com/nion-software/nionswift/pull/1073

However we're not currently happy with the two button concept so we're going to take another look at that first before moving this forward.

After discussion on this issue we've got a proposed revised spec that @Tiomat85 is going to code too...
