Menu item for common viewpoints

[pocomane]

This is a first implementation of the feature described in issue #94

[DeveloperPaul123]

Overall, looks pretty good. I'm working on some minor changes and then this should be good to merge. The menu is a little cumbersome if you're changing views often. Maybe a popup menu like in solidworks or keyboard shortcuts would help in this regard. Any ideas?

[DeveloperPaul123]

Maybe something like this

@pocomane I added some animations to polish the feel of the changing views. Give it a try and let me know what you think.

[DeveloperPaul123]

@pocomane Have you had a chance to take a look at this?

[pocomane]

The nested menu, also if not very fast, let's me to align the view to the axis, that was absolutely impossible before. That was the sole issue I was trying to solve. Switching easily from one view to another is a different issue.

For the "Popup menu", do you mean a menu-bar + a popup and so on? I do not know if it matches the "Minimalist" philosophy of fstl. Rather I wold go for keyboard shortcuts, that will really speed-up the process, and they are still discoverable the first time from the menu.

About your changes @DeveloperPaul123 , I can not compile them. This is the first part of the complain by gcc:

Hi @pocomane

Sounds good, I was mainly referring to the animation changes I made but I see you can't compile the changes. I will investigate.

[DeveloperPaul123]

@pocomane Can you try out #110 and let me know if it works for you? I cherry picked your changes into a new branch so that I wouldn't have to push changes to your master branch and I could integrate the latest changes from fstl/master as I've merged in a couple other PRs.

[DeveloperPaul123]

Merged as part of #110
