Test plan item for #21849

• anyOS @weinand
• anyOS @dbaeumer

Complexity: 3

There are two new minimap modes that can be set to editor.minimap.mode: contain and cover.

Please check:

• using render characters or render blocks
• using editor.minimap.scale which then acts as a maximum scale
• using short, medium sized and large files (where sampling kicks in)
• try editing the file and check how the minimap adjusts (the sampling one is most interesting)
• please keep an eye out for any rendering artefacts
