Transparency for Folder-Thumbnails

[fishgod]

Hi, I haven't been here around quite some time but using XYplorer and seeing all the improvements going on is still a great pleasure for me on every day.

But what bugs me since years is how XY handles Thumbnails for folders in combination with transparent images (PNG):
Folder 1 in the attached screenshot shows the current situation for my dummy-image (just a circle on transparent background).
Folder 2 shows what I wish for. (in the screenshot it's faked by just adding the gradient directly to the image, not having a transparent image anymore)

I think the proposed behaviour should be the default for "Transparency: Neutral" because currently the "Neutral"-Setting acts excatly like "White" for folder-thumbs.
