Was this just to make the tests pass better? The change is kinda out of nowhere ;D

Yes, I added a test that verifies how the bullet behaves when there's no font (to make sure I'm not breaking anything), and it turned out the bullet was misaligned by one pixel 😅

just to be sure, did you test some SWFs like this?

Generally yes, I made sure that Flash behaves this way and most SWFs from my text collection work.
However, I've just remembered one SWF that used a wrong font: #14740, and unfortunately checking it now, it turns out the text disappears in it. Which makes sense, because now Ruffle somehow fails to load the embedded font and falls back to a device font :/
So I guess there are (and probably will be) cases when Ruffle fails to load an embedded font. Some probably are hard to spot.

Apparently it should be 36px, not 35px.
Flash Player does not show any text that requires an embedded font that is missing.
This test verifies how bullets are rendered and which font should be used.
This test verifies how FP behaves when we want to get some metrics related to text that uses a font which is missing.

As we now support DefineFont4, we're safe to remove the fallback device font.
