If you edit an actor name, then delete the actor - it fails to be removed from the map in the editor. This is because the actor previews are keyed by ID. Editing their name edits their ID and breaks the stability of their hash code. This unstable hash code means the preview will now fail to be removed from collections, even though it's the "same" object.
Fix this by making the ID immutable to ensure hash stability - this means that a preview can be added and removed from collections successfully. Now when we edit the ID in the UI, we can't update the ID in place on the preview. Instead we must generate a new preview with the correct ID and swap it with the preview currently in use.
Some existing widget are too small to accommodate their text. Adjust their sizes to fit. Text can be rendered outside the widget bounds so visually this often has no impact, but adjusting this now will help in the future for checking translation text for other languages fit in their widgets.
Reduces size used for png files from 13,366,660 bytes to 13,055,285 bytes in total. Changes size used for oramap files from 2,601,027 bytes to 2,605,779 bytes in total (contained PNGs are smaller, but the oramap zip wrapper didn't compress as well). This slight filesize improvement doesn't noticeably impact loading times.
zopfilpng is used for compression with the following command line:
'zopflipng.exe -y -m image.png image.png'
This follows on from 78bef8a98f and bc5e7d1497. Except now that the PNG decoder supports bit depths of 1, 2 or 4 we don't have to preserve the original bit depth of the image, allowing for more compression.
The oramap files were updated by:
- Running utility command "<mod> --unpack-map unpack" for each mod.
- Compressing the png files using the command above.
- Running utility command "<mod> --unpack-map repack" for each mod, except in Map.Save the line `if (!LockPreview) { var previewData = ...` is replaced with `if (false) { var previewData = ...` to save the existing optimized image on disk rather than generating a fresh preview.
