(Imagick) Suggestion to allow setting filter type and blur for better resize quality.

[skiingdomo]

Hi,

Just a suggestion for the Imagick implementation in imagecow. Specifically, in Libs/Imagick.php, on line 229 where it uses scaleImage():

if ($this->image->scaleImage($width, $height) !== true) {
https://www.php.net/manual/en/imagick.scaleimage.php

ScaleImage() does not allow configuration of the filter or blur setting. The function resizeImage() is very similar but allows for changing these settings.
https://www.php.net/manual/en/imagick.resizeimage.php

For example we set the filter to Lanczos, and blur to 0.8:
if ($this->image->resizeImage($width, $height, \Imagick::FILTER_LANCZOS, 0.8) !== true) {

This vastly improved the quality of resized images. Especially ones with text on them.
