Gtk3 HiDPI: menus

[DarthGandalf]

Brief summary of issue

Steps to reproduce the issue

1. export GDK_SCALE=2
2. Try to take picture of menus (with nested/cascaded submenus), or a section of a window
3. See that the result doesn't look right:

Extra information, such as Shutter version, operating system and ideas for how to solve:

Subwindows actually stopped working a long time ago, so the reason is not in the recent changers (after 0.94), here's a (very old) report: #25 Menus and submenus are working in 0.95. But I think, the breakage is not a major thing compared to the progress made since 0.95. If it turns out to be a hard nut to crack, maybe just remove the corresponding button and menu entries for the time being?

@Photon89 thanks for link. I agree that it may be removed.

Menus is a different case. They work fine in 0.94.

[Photon89]

Agreed. Though, if the menus bug is hard to fix with the changes made after 0.95, I think it would be fine to remove them as well, temporarily.

I am currently trying to run the latest git commit, need to package perl-gtk3-imageview-8 and, possibly, other deps first though.

The current workaround I made for the menus bug is to show the warning with the advice to disable scaling. I think it's better than removing the feature altogether.

[Photon89]

I see, I missed the part where you said that the bug only appears on HiDPI setups. Then your solution is much better than just removing the functionality completely.

[DarthGandalf]

I've disabled the sections buttons

To clarify: this was not a problem in 0.95 because gtk 2 doesn't have a concept of automatic UI scaling
