bug#59944: Transparency with alpha-background doesn't work well with PNG images on Emacs 29.0.60

[Satya Prakash Dahal]

PNG images with a transparent background are not transparent. 

Look at the image emacs_png_bug.png on the attachment.

This is my first bug report. If I am missing something please let me know.

Below are the commands i used to compile the emacs.

git clone https://github.com/emacs-mirror/emacs.git

cd emacs

./autogen.sh

./configure

./configure --with-mailutils && make
make install
