Relpace classic gallery scripts with modern mode

[PaulWessel]

Let the gallery use modern mode

With the push to modern mode it makes sense to simplify our gallery by using modern mode as well. Right now, only 13 of the 50 scripts have a modern mode equivalent in test/exmod. Perhaps we should make a push to convert the rest in test/exmod first and then we can switch classic and modern when ready?

Thanks, just add in test/exmod for now. To avoid us both doing the same, how about you start on the lower half (1-25) and I start 26-50?

OK.

@PaulWessel I think we should NOT add the modern examples to test/exmod.

The examples are pretty large (~40 Mb). Converting these examples to modern mode and adding them to test/exmod means adding another 40 Mb to the repository.

Although the classic examples will be deleted someday, the 40 Mb files always stay somewhere in the git history. Currently, the repository size is as large as 700 Mb, and the .git directory is almost 500 Mb.

We should try our best to avoid adding more large files to the git history.
