PFD overlay labels need some transparency

[pryre]

Tell us a bit about the feature:

• What problem does it solve? Visibility
• What does it do? Visibility
• What flight stacks must it work with? (All)
• Relevant vehicle types? (All)
• Are there other systems that have this feature? ALL
• What communication/integration standards does the feature rely on (e.g. MAVLink commands etc.) Visibility

Any additional context you can provide will make the feature easier to evaluate (e.g. mockups, detailed specification, etc.) Visibility
