I thought dvisvgm might, for PS-to-SVG conversion; but having compiled the development Ghostscript code, it seems dvisvgm is unaffected by the change and works with gs exactly the same as before.


thank you for the heads up and for testing dvisvgm with the GS 
development version. I also performed some tests with it and can't find 
any issues at the moment either. However, dvisvgm uses setpagedevice in 
conjunction with /OutputDevice to extract bitmaps from PS/EPS files.
According to the GS docs, this should lead to an error if the used 
devices are not specified with --permit-devices. But the GS development 
version of 10.4.0 still works as before without this command line 
parameter. Maybe -dNOSAFER disables the additional checks. I guess I 
need to investigate this in more detail.
