Bug: DC_Folder does not check for gdlib when generating thumbnails

[Toflar]

This means that gdMaxImgHeight and gdMaxImgWidth are considered even though I use Imagemagick.

[DanielSchwiperich]

composer.json requires ext-gd so running gdlib is necessary I assume

[Toflar]

Gd is absolutely not a requirement. That's another bug then :)

ext-gd is a requirement until Contao 5.0, see #533 (comment)

But the requirement of GD has nothing to do with the fact that we should ignore gdMaxImgWidth/Height if Imagick or Gmagick is used by the image services. We do this already in the LegacyResizer in src/Image/LegacyResizer.php:122

How can we check the implementation here?

With \System::getContainer()->get('contao.image.imagine') instanceof \Imagine\Gd\Imagine
