Issue with Text Rendering using External Fonts

[mikay1337]

I'm encountering an issue with text rendering when using an external font. The original branch displays the text correctly and functions as expected. However, when I switch to the fork branch, the text alignment appears to be different, causing inconsistencies in the rendering.

Steps to Reproduce:

Switch to the original branch and observe the text rendering with an external font.
Switch to the fork branch and compare the text alignment with the original branch.
Notice the differences in text alignment between the original and fork branches.
Additional Details:

The external font being used: Robotto.ttf
Screenshots showcasing the issue on both branches:

This issue affects the consistency and appearance of the text rendering, particularly when using external fonts.

I decided to stop supporting non monospace fonts for now, as it breaks the whole meaning of columns in the editor. So that's expected.

Perhaps we should document this and close as wont-fix.
