PHP 8.1 deprecation warning - float to int in imagecopy setCanvas

Problem/Motivation

    if (imagecopy($this->getToolkit()->getResource(), $original_res, $arguments['x_pos'],  $arguments['y_pos'], 0, 0, imagesx($original_res), imagesy($original_res))) {
      imagedestroy($original_res);
      return TRUE;
    }

Imagecopy requires that the 3th and 4th argument are an integer.

But when the argument is a float it throws a warning.

Why is a float?:

function image_filter_keyword($anchor, $current_size, $new_size) {
More specifically:

    case 'center':
      return $current_size / 2 - $new_size / 2;

When (580 / 2) - 431/2 : 74,5
So this creates a float in function: public function applyEffect(ImageInterface $image) { in SetCanvasImageEffects.php

Patch attached to resolve this warning

Remaining tasks

Review

Question: We could also solve it inside of "SetCanvasImageEffects" but aren't we limiting the output then by default? (In cases we don't want it ?)
