Consistently round glyph advances in the SFNT font backend

* src/sfnt.h (SFNT_ROUND_FIXED): New macro.

* src/sfntfont.c (sfntfont_get_glyph_outline): Don't apply
advance width distortion before the glyph is instructed or
decomposed.  Round advance width as measured between both
phantom points subsequent to instruction code execution.
(sfntfont_draw): Don't take the advance's ceiling when advancing
origin point.

(cherry picked from commit cd91ecedcbdf03ae13f45cb173360b11f13a0bc0)
