magick: Ignoring invalid time value `test.png' @ warning/png.c/MagickPNGWarningHandler/1744.
The same warning is issued when I use other IM native images like "gradient:" or "label:" as input images and save as a PNG.
I also get that warning sometimes if I use a PNG image as input and save as a PNG, but it doesn't always happen, and I haven't figured out what triggers it.
