    [truetype] Increase precision of font variation (#54371).
    
    This patch make FreeType use font units in 26.6 format internally
    instead of integers.
    
    * src/truetype/ttgxvar.c (FT_fixedToFdot6): New macro.
    (TT_Vary_Apply_Glyph_Deltas): Add argument to output unrounded font
    coordinates.
    * src/truetype/ttgxvar.h: Updated.
    
    * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Use
    `extra_points2' array to temporarily hold unrounded point
    coordinates; use them to compute scaled coordinates and linear
    advance width and height.
    (load_truetype_code): Adjust similarly.
