Illegible text due to no drop shadow, or outline

[fluffyfreak]

Observed behaviour

The white text is almost unreadable

Expected behaviour

The the text has a drop shadow or outline rendered to distinguish it from the background

There are a number of open issues and alternative options of Dear IMGUI that might help. Using a drop shadow or signed distance field font rendering to provide contrasting backgrounds for text.

Steps to reproduce

Fly your ship to the nearest star or planet with a bright enough surface and orient the ship so that the text on the HUD is over the star/bright surface.

Assignees

I've pre-assigned it to people who might be most interested/involved in fixing it... 'cos I can 😝
Feel free to re-assign if not appropriate.

Previous issues and fixes

Also see very old PR #325 which was to fix issue #39
So we've actually regressed slightly in this area.
