Text scale?

[chlobes]

I'm trying to align text rendering with planar rendering, drawing some text on top of a rect to make a button for example.
But text rendering seems to use a different scale than pixels, the text appears much smaller than it should and offset up and left.
What determines text scale compared to pixel scale and how can I read or write it?

window.draw_text(
"Hello!"
&Point2::origin(),
60.0, // Scale
&Font::default(),
&Point3::new(0.6, 0.6, 1.0), );

Yes, I am aware that is how you scale the text, however as I said the text uses a different scale than pixels, depending on the screen size, making drawing a simple button impossible. I have since moved on to libraries that support this.
