Gramps 3.4.3-1 missing fonts and png export for graphs

I just installed the above and I'm lacking the export formats for "Reports -> Graph -> Relationship Graph", I had the AIO version installed before but I prefer portable programs so I switched, but now I can't export to anything, not .svg nor .png, only the .gv format that's useless to me.

So how can I add whatever's missing there into the portable version?

The other problem I have with both versions is how the heck do I install new fonts to that export thing? I already tried to find something with google but I seem to be the only one that has that problem.
I only have the two default fonts for choice and they both look horrible on png as some letters have too much free space behind them and some not enough.
