[BUG] Visualisation Disappears Off Screen on Small Screens or With Larger Trees

[rmberriman]

Describe the bug When opening a repository on a smaller screen, the visualisation disappears off screen and has to be dragged back into sight. This could be extremely confusing as new users may think the graph has disappeared - and may not realise that it can be dragged into sight. If this is expected behaviour, could add an unobtrusive popup telling the user to drag to see the graph.

When viewing a larger tree, the majority of the tree will be out of the current viewing window.

To reproduce Steps to reproduce the behavior:

1. Open VisualGit on a smaller screen (i.e. 13" -14")
2. Login to VisualGit
3. Clone repository from web
4. See error

Expected behavior / Acceptance criteria

• The graph should be visible without dragging into sight.
• Larger trees scale out (to view the full tree - up to a certain point) and users can zoom in

Screenshots

Desktop (please complete the following information):

• OS: Windows 10
  • Screen Size: 14
  • Window Size: VisualGit was full screen on laptop

I have experienced a similar scenario but with larger trees, the majority of the tree will be out of the current viewing window. It might make sense to change the tree to scale out (up to a certain point) and allow the user to zoom in. I think this would make sense to be merged into this issue if we decide to make that change.

There is not currently an issue created for the scenario I outlined above.

I think that is a good idea - I will update the issue description!
