Font problem with png terminal 2.9.17+

[Tatsuro MATSUOKA]

Hello

The png terminal can be enhanced mode.

       G N U P L O T
        Version 4.2 patchlevel 2      
gnuplot> set terminal png enhanced
Terminal type set to 'png'
Options are 'nocrop enhanced medium '

Help
      set terminal png 
             {{no}transparent} {{no}interlace}
             {{no}truecolor} {rounded|butt}
             {tiny | small | medium | large | giant}
             {font <face> {<pointsize>}}
             {size <x>,<y>} {{no}crop}
             {{no}enhanced}
             {<color0> <color1> <color2> ...}

I am against to list out png terminal from enhanced list.
The png terminal is the most useful bitmap terminal for the gnuplot.

Alternatively, the OpenSymbol font, distributed with OpenOffice.org as "opens___.ttf", offers the same
characters. Microsoft has distributed a Symbol font ("symbol.ttf"), but it has a different character
set with several missing or moved mathematic characters. If you experience problems with your default
setup (if the demo enhancedtext.dem is not displayed properly for example), you probably have to
install one of the Adobe or OpenOffice Symbol fonts, and remove the Microsoft one. Other non-conform
fonts, such as "wingdings" have been observed working.

Open office have OpenSymbol.ttf.

But Note that it has a different character set from Microsoft symbol.ttf described above.
