Describe the bug
When using a pixel-style font like Cozette or Ark I notice that the edges of the font get kind of blurred slightly most of the time, though if you position and size the window/widget to just the right spot the edges will be clear.

Here's a screenshot:

The effect is subtle, but zooming in makes it more obvious:

But the button text happens to line up fine and end up clear:

To Reproduce
It seems to be reproducible by simply uploading a font such as font like Cozette or Ark and placing a label.

Expected behavior
The edges of the font should stay crisply lined up with the screen's pixels

Desktop (please complete the following information):

• OS: Ubuntu 20.04

I wonder if this might be due to linear filtering on the font texture. 🤔 It might be simple enough to allow you to specify that a certain font should have it's texture generated with nearest filtering mode. We would have to test to see if switching the filtering mode will fix the issue.
