Using --width leaves margin on the right

[beberlei]

Describe the bug

I want to embed the images into a presentation, using placement snapping to center code images so that I can have multiple after each other without the window "hoping" around. However the generated images using a fixed width have transparent margin on the right, so that I can't center it with Powerpoint correctly.

To Reproduce

{
  "window": false,
  "width": 1600,
  "height": 900,
  "border": {
    "radius": 32,
    "width": 4,
    "color": "#515151"
  },
  "shadow": false,
  "padding": [20, 20, 20, 20],
  "margin": "0",
  "font": {
    "family": "Source Code Pro",
    "size": 48
  },
  "line_height": 1.2,
  "show_line_numbers": true
}

file:

<?php
// writes "/tmp/test.txt" into stat cache
touch("/tmp/test.txt");

// file existance is known from stat cache
if (file_exists("/tmp/test.txt")) {
}

// load something else from filesystem
$stat2 = stat("/tmp");

// not in cache anymore, load from filesystem
if (file_exists("/tmp/test.txt")) {
}

command:

freeze --config=custom.json --theme=dracula --language=php stat1.php -o stat1.png

Expected behavior

image with terminal window at 1600px width.

Screenshots

Additional context
Add any other context about the problem here.

More context, the transparent margin on the right is 148px wide, and if i re-render with -W 1400 instead of 1600 this margin stays exactly the same.
