Trying to make my own powerline glyphs - background bleeds over top border

Hey there, I'm trying to make my own "slant" style powerline glyphs. I figured out how to do it in fontforge, but the background color bleeds over (or out from under) the powerline glyph at the top:

(the first glyph has a green fg and blue bg, and you can see the 1px blue line atop the glyph).

I tried extending the top of the glyph straight up by adding a full-width block at the top, but that didn't change anything.

Is there anything that can be done about this or is it a general limitation with fonts or the xft rendering used in urxvt (this doesn't seem to happen in lemonbar)?

weeeeeelll.... nevermind. I increased the height of the top-block (by a lot) and now it works.

Good. Do you plan this in core?

Response per mail got lost apparently. I didn't consider it, but if you want to have them in there I could provide an alternate set of glyphs for the powerline/fontpatcher repo and/or a set of combined fonts with my glyphs.

Do you mean, that both old and new glyphs will be available in fontpatcher/combined fonts? That would be good.

If you want, I can add you to fontpatcher as a collaborator; in any case I cannot review much there, except for the code style.

I don't know how much unused glyphs there are in the User unicode block, but if there are four left I could add these alongside the original ones and provide a unicode-alt theme that uses them instead for example.

with my font stack http://jrgraphix.net/r/Unicode/E000-F8FF shows that E0E0-E0E3 are free, I could use those maybe.

There is more then one Private Use Area: U+F 0000-U+F FFFF and U+10
0000-U+10 FFFF are additional ones. I do not know how good different
terminal emulators support displaying characters from these areas
though: e.g. echoing U+F 0000 clearly shows that zsh (5.2) thinks that
this character has double width, while konsole displays it as single
width which makes it impossible to use U+F0000 for zsh prompt (same
for bash-4.3_p42-r1). Python-3.4.3-r1 and -2.7.10-r1 say that width of
this character is ambiguous (AFAIR they are right here).

Also no idea how @Lokaltog was choosing what code points to use for
existing glyphs.
