Support font size in pixels in addition to points

[lovelymono]

Problem description

Currently Sublime Text 4 uses points to describe font size, such as in Preferences: Settings:

{
  "font_size": 10
}

This is rather counter intuitive, and worse, makes setting a precise font size rather difficult (for example, to get font size of 10px with MonoLisa font on Linux, I need to set font_size to 7.5. It also makes setting the font size across different applications, fonts, and operating systems problematic, as outlined by @tonsky in his blog post: https://tonsky.me/blog/font-size.

Preferred solution

Allow specifying the unit in the font_size option, such as

{
  "font_size": "10px"
}

or

{
  "font_size": "10pt"
}

in addition to the current syntax.

Alternatives

An alternative would be to add another setting, pixel_font_size, which would override the font_size option, and set the font size in pixels, rather than points, such as

{
  "pixel_font_size": 10
}

Additional Information

None applicable.

It's been two weeks without any comments, nor it has been assigned any labels, just wanted to make sure that it wasn't missed by the maintainers.

Given that it's 2025, yes, this probably has been missed by the maintainers!
