Control of Yellow boxes and High DPI Displays

[rgleason]

Also need better control of the POIs etc display.

• Control of amt of info displayed, then click?
• Selection of info.
• More compact display, that is better formatted for each type.
• Size of text adjustments?

I and others have high DPI displays and that causes troubles with text, spacing, cursor size, line thickness etc.
These adjustments are not transmitted to each plugin via the API.
Maybe they should be but they aren't.
