pgtk does not do subpixel rendering

[Torsten Bronger]

Hallöchen!

Everything observed with Ubuntu 33.04’s Wayland configuration:

Compiling Emacs with --with-pgtk switches off subpixel rendering,
making everything slightly more blurry.  Playing with other options
(e.g. --with-cairo) did not bring it back.  Only --with-x instead of
--with-pgtk restores subpixel rendering.  Is this a bug, a known
limitation, or a configuration error on my side?  The complete
configure command is:

./configure --prefix=/usr/ --mandir=/usr/share/man/ --infodir=/usr/share/info/ \
            --with-x --with-x-toolkit=no --with-xpm --with-jpeg --with-tiff 
--with-gif --with-png \
            --with-file-notification=inotify

with X and

./configure --prefix=/usr/ --mandir=/usr/share/man/ --infodir=/usr/share/info/ \
            --with-pgtk --with-xpm --with-jpeg --with-tiff --with-gif 
--with-png \
            --with-file-notification=inotify

with pgtk.

Torsten.
