will dvisvgm ship with support for PostScript specials (Windows, Mac OS)?

[jfbu]

Hi,

I apologize in advance for vagueness: a friend of mine
on Windows reported, if I understand correctly, that
TL2018 dvisvgm.exe does not work with PostScript specials.

I don't know whether he tested out the TL2019 pretest.
The darwinglegacy one seems to have no such support either

$ /Library/TeX/texbin/dvisvgm --version=yes
dvisvgm 2.6.3
-------------
brotli:    1.0.7
clipper:   6.2.1
fontforge: 20160721
freetype:  2.9.1
kpathsea:  6.3.1
potrace:   1.15
xxhash:    0.6.5
zlib:      1.2.11

It is very useful to have dvisvgm supporting Postscript specials
like in this case (MacPorts dvisvgm)

$ dvisvgm --version=yes
dvisvgm 2.6.2 (x86_64-apple-darwin13.4.0)
-----------------------------------------
brotli:      1.0.7
clipper:     6.2.1
fontforge:   20160721
freetype:    2.9.1
Ghostscript: 9.26
kpathsea:    6.3.0
potrace:     1.15
xxhash:      0.6.5
zlib:        1.2.11

What is then status on Windows (and Mac OS) for TL2019 ?

Best,

Jean-François
