This change would still break the thumbnailing system built into
libgimpthumb. This code uses the PNG module from gdk-pixbuf to load and
save thumbnails and it relies on the ability to read PNG text chunks
from PNG images and to set the PNG text chunk when creating PNG files.
So if you are taking away this functionality from the PNG module on the
Windows platform, then this would be a major regression.

It's also important to support the JPEG quality option on the JPEG save
module. How is that handled in the GDI code?
