Is there an emacs version that supports displaying png / tiff images on the toolbar instead of only xpm?
On Mac the Mitsuharu Yamamoto version display TIFF images without any issue. I tried modifying tool-bar.el to add the tiff and png support but did not work. The emacs version on windows is the GNU one with dependencies installed and I can display PNG images in the buffer, the issue is only in the toolbar.
I was wondering if the image support for the toolbar is coded directly into the emacs code and that is why the GNU version does not recognize the modified tool-bar.el
