@EbenSorkin This is work in progress, please don't merge yet.

Now mastering and finalising the sources.

@EbenSorkin This is good to merge now

I have fixed some minor interpolation issues in the fonts, in connection with sources convertion to glyphs app.

There remains a problem I don't know how to fix yet.

Previous version — no ccmp = no problem

New Glyphs version Regular — ccmp works fine

New Glyphs version Italic — ccmp doesn't work properly

/cc @kalapi @schriftgestalt Do you know why the Aringacute isn't placed properly? This glyph isn't in the font, but is produced thru mark positioning.

@alexeiva The combining marks in the italics don't have a 'top' anchor and thus no resulting mkmk. Also, not entirely connected, the combining marks have advance widths (in both sources).

[alexeiva]

@kalapi Thanks, will try that.
Combining marks have advanced widths in sources, but on TTF export glyphs zeros them automatically.

Also, not entirely connected, the combining marks have advance widths (in both sources).
Yes, as @alexeiva said, on export, they are set to zero width. Zero width glyphs are difficult to edit in Glyphs because they sit on top of each other in the edit view.
