UI elements occlude tree when using "Print to PDF"

[rreinecke]

Describe the bug The buttons on the left hand side can overlay the tree when printing to PDF.

To Reproduce Steps to reproduce the behavior:

1. Open a tree.
2. Print to PDF (printing in landscape mode can help a bit to reduce this issue)

Expected behavior The current export button opens a new tab that shows only the tree and legend, without the forester header (Documentation, Github etc.) and the buttons. It then automatically triggers the print dialog of the browser.

How the page looks in the print depends on the paper size, as the browser re-draws the page. There is only so much that can be done about this, but I think a good workaround for now would be the following:

• [ ] Open the print dialog automatically when clicking the button
• [ ] Hide all elements except the tree and the legend to make as much room as possible
• [ ] Recenter the tree in the new space (possibly scale it to fit the size of the paper)

Default options for printing (don't know whether these can be set)

• Largest possible paper size
• Orientation based on aspect of the tree
• Include background (otherwise the colors in the legend are not shown)
