* generic/tkImgPNG.c (WriteIDAT): [Bug 2984787]: Use the correct
flushing semantics when handling the last data from the image. Without
this, many PNG readers (notably including Firefox) refuse to show the
image and instead complain about errors.
(ReadIDAT): Added sanity checks to ensure that when we've got bad data
of the sorts of forms we were previously generating, we detect it and
error out rather than silently failing.
(WriteExtraChunks): New function to write in some basic metadata.
