[freetype2] master ecfdfd4: [truetype] Make blend/design coordinate round-tripping work.

[Werner LEMBERG]

branch: master
commit ecfdfd4498d6c1313b3faaa9d7cf1917e4be98c5
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [truetype] Make blend/design coordinate round-tripping work.
    
    Behdad reported that setting blend coordinates, then getting design
    coordinates did incorrectly return the default instance's
    coordinates.
    
    * src/truetype/ttgxvar.c (tt_set_mm_blend): Fix it.
