Feature request: Method to save current configuration as Display.globals

[gdevenyi]

It would be nice if I could configure the display defaults using the menu system and then dump that config to a file, so it will be reloaded on start.

Similar to the window config currently offered.

Connected to #32

@gdevenyi Done.

[gdevenyi]

Thanks.

I expected based on older notes that a Display.globals in $HOME would be loaded, but that doesn't seem to be the case? Did the location of the location move? (I'd prefer something lik ~/config/minc anyways...

[rdvincent]

Display.globals is generally either in $HOME or in the directory of the executable. Either one should work. The save feature I implemented just saves to an arbitrary file - it's up to the user to put in the the standard place. If that proves unwieldy or confusing, I can force it to save in the "official" place under the standard name only.

[gdevenyi]

Okay, so I made some changes and saved the globals to $HOME/Display.globals

Upon running again, I don't get those values back.

[rdvincent]

OK. Depending on the values you set, this could be "correct" behavior. Unfortunately, many of the globals are used to set initial values of other parameters. Changing the parameters within Display does not imply changing the globals. If you have specific variables you want to be able to save, let me know what they are and I'll check it out.

Okay, so, this originally triggered by #32

So I change the opacity to 0.4, save globals, and find that my globals file still has the (new) default of 0.5 saved. - I guess this is a bug

Similarly, I change the colour map to grey, I was hoping that the map would be saved in globals. - This may be because it's not saved at all
