thumbs.php: Thumbnails for images with transparent background look ugly
0%
Description
When viewing a thumbnail generated by thumbs.php for a file in the backend, the background of transparent images gets filled and looks really ugly. This seems to be related to a downsampling of the image's colordepth. This downscaling is done in t3lib/thumbs.php, presumably to save disk space and bandwidth.
As lines are faster and disks are cheaper now than 2003, this is unneccessary. So the whole downscaling for GIFs and PNGs should be removed. Attached patch fixes this.

In the attached file this issue does not seem to occur. Under which circumstances is this problem visible. Can you upload an example image and information about the used image manipulation software?

the attached gif does not work without the patch, but after applying it works.
