Improvements to decsender/cyrtic in cyrillic "ц"
Strange and unnatural descender of the cyrillic letter "ц". It is obvious to russian-speaking people. Too compressed in 100-300 weights and too huge in 700-900. Weights 400-500 are acceptable. At the same time, a similar letter "щ" has almost normal descender (probably not perfect but pretty good). You can take it as an example to follow (including a slight skew).

Environment
- OS: Windows 7
- Software: Any
- Version of font: 3.3;20b39288a
There's a problem only with small «ц» letter. Capitalized letter works normal and has a skew
Maybe this helps.

@rsms is it possible I help here not having Glyphs app?
Maybe I can fix ц and щ in Inter UI glyphs file, and you copy-paste them to Glyphs after?
