PNG Textures do not work

[griestopf]

PNG Textures have different effects when used as albedo color input. Sometimes they result in a bluish albedo with otherwise correct lighting calculation, sometimes they result in bright white.

TODO:
Update SixLabors from myget (not nuget!) (use latest pre-release with fix): https://www.myget.org/feed/sixlabors/package/nuget/SixLabors.ImageSharp.Drawing

• Add myget as cache in nuget.json
• Pull/use latest version
• Update to latest API
• Test error with latest version

@griestopf Please test with: https://github.com/FUSEEProjectTeam/Fusee/tree/feature/395-update-latest-sixlabors-fix-png

or provide test data, please.

Edit: Does not work, needs re-writing of FontImp in order to work properly. New API.

Blender file:
BrickCubeBlend.zip

Fusee file:
BrickCubeFus.zip
Warning: Setting the absolute path as a program parameter to FUSEE player does not work with the above .fus file since the asset manager currently does not try to find texture assets in the fus-files directory (another bug).

[griestopf]

Action: Wait for next Pre-Release containing the PNG fix and adjust FUSEE to breaking API changes.

Should be fixed with #466
