That's surely a wishlist item for CC4, right? :)

Being able to load/save presets would be nice.

I revisited this and everything keeps suggesting it's just due to differences in CC2 and CC3 file formats... and it's possible there's no solution (if I wish to keep opening the edited maps in FRIA; note that CC3+ has no problems).

Anyway, I didn't include screenshots from the listings in my original post, so I opened an original FRIA map and LIST'ed the entity with a Symbol Fill style..

As soon as I save it in CC3+, as a CC3 map, I get this from FRIA:

Same FS number, but it's now identified as "Hollow". Weird, right?

The only truly different thing I tried this time, just to rule things out, was adding an extra "Hollow" entity. FRIA reports as:

There's several maps that would benefit from minor fixes and edits, so I kinda keep hoping there's a way around this. Or maybe I should just browse the FR maps with CC3+.

This blog post might also be useful:

It doesn't mention directly sizes, but rather the layouts that resulted.

Come think about it.. I did experience unusual lag (compared to running natively on Windows) while opening a very large map. My best guess would be that wine still has some shortcomings while drawing on screen.

Oh, I'm using Fedora, which has a fame for being bleeding-edge. I don't think it would make much of a difference though. And do note that the results I posted in the link on my previous post is for version 7.12. I wouldn't worry too much about versions tbh.

Ralf did a live mapping session on creating your own symbols:

It starts describing how to create vector-based (very important to understand how symbol catalogs work), and then around 42:05 it covers importing PNGs as symbols.
