Summary: replot stream not working on png/psc devices

Initial Comment:
The replot of a stream does not work when using png/psc devices.
To reproduce: start example x01c -save toto.ps
set the asked device to png / toto.png
The first plotted plot (toto.png) is fine, the second one, plotted using stream 
replot (toto.ps) is black.
Same thing occurs if you edit x01c.c to plot toto.ps first, then toto.png 
(toto.ps is then fine, when toto.png is completely black).
This bug occurs with plplot 5.9.4 and 5.9.5, with the following cmake options:
-DUSE_RPATH=OFF -DDEFAULT_ALL_DEVICES=ON -DCMAKE_INSTALL_LIBDIR=/usr/lib64 
-DHAVE_numpy=ON -DHAVE_QHULL=ON -DHAVE_PTHREAD=ON -DHAVE_FREETYPE=ON 
-DENABLE_ada=OFF -DENABLE_f77=ON -DENABLE_java=ON -DENABLE_gnome2=ON 
-DENABLE_octave=OFF -DENABLE_pdl=ON -DENABLE_python=ON -DENABLE_tcl=OFF 
-DENABLE_itcl=OFF -DENABLE_tk=ON -DENABLE_itk=ON -DENABLE_wxwidgets=ON 
-DPLDpdf=ON -DPLDpsttf=ON -DPLDpstex=ON -DPLDlinuxvga=OFF -DENABLE_f95=ON 
-DPL_FREETYPE_FONT_PATH:PATH=/usr/share/fonts/freefont-ttf -DENABLE_pygcw=ON 
-DPLD_memcairo=OFF -DPLD_extcairo=OFF -DPLD_pdfcairo=ON -DPLD_pngcairo=ON 
-DPLD_pscairo=ON -DPLDsvgcairo=ON -DPLDxcairo=ON -DCMAKE_BUILD_TYPE=Gentoo 
-DCMAKE_INSTALL_DO_STRIP=OFF 
I tried to use pngcairo and pscairo instead, which leads to a segfault when 
doing several plots (a bug reported on the mailing list, but apparently without 
any solution yet).
Thanks for your help,
Fred.
