info attribute. display of text in opengl or with a egui popup.

[coderedart]

The info attribute needs us to show text. we can do this in two ways.

1. Add a glyph texture dependency and start rendering opengl text. this is more complicated, but we might eventually need text rendering anyway.
2. just use a simple egui area/window to display text. we can keep it to a side, or make a notification-ish floating and fading away thingy or just keep a seperate dedicated window for this which gets a text message of the info string.
