 #!CommitTicketReference repository="" revision="59589"
 Media: improve Imagick handling of colors and alpha channel for PNG image
 uploads.

 Fix an issue where index color (8 bit) PNG uploads were output as true
 color (24 bit) PNGs, significantly increasing their size.  When using
 Imagick, PNG output images will now match the colors of the uploaded
 image.

 Also, correct handling of PNG alpha channel information so it is preserved
 in output images.

 Fixes #36477.
