Add option to hide cursor entirely

[HappyHippo77]

I'm partially making this request as I'm encountering an issue similar to #338, in which the cursor does not perfectly line up with the pen's position. The cursor effectively refuses to follow the pen if fine movements are made, although it does roughly line up when moving in broad strokes. The location of writing is completely unaffected however, and I personally find the cursor to be distracting and unnecessary for my use case, so a simple solution for me would be to simply hide the cursor.

Unfortunately, this is not, as far as I can tell, currently an option. There is an option to hide the cursor when writing, but not to hide it entirely. I suspect that this wouldn't be a particularly difficult option to add, but I am an absolute noob when it comes to Rust and I have no experience with GTK at all, so figuring out how to add that feature myself is a bit tricky.

Which OS you use? In recent versions of Fedora Linux there is a bug that when I make rnote fullscreen, the cursor is hidden.

I use Fedora as well, Workstation specifically. I haven't encountered that bug personally, perhaps it's a hardware issue? Regardless, I'm not sure that is really related to this issue, as this is a feature request, not a bug report, and relying on a bug that will likely be solved in the future to provide the feature would be rather... suboptimal.

I am using Fedora Linux Workstation with Gnome desktop environment. What hardware are you using. I am using XP-Pen Deco and I can't see any cursor when I go to full-screen in rnote.

[Edit]
Good news! I just tested it again, going to full-screen in rnote. The problem does not exist anymore. I don't know when it got fixed.
