[truetype] Clean up phantom point accounting. This formalizes that the phantom points appended in the outline do not increase its point count, nor are they tagged or included in any additional contours. Only their coordinates are stored. They are counted in the glyph zone, however. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Infer `n_points` from the outline size plus four phantom points. * src/truetype/ttgxvar.h (TT_Vary_Apply_Glyph_Deltas): Remove this argument. * src/truetype/ttgload.c (tt_prepare_zone): Add phantom four. (TT_Process_Simple_Glyph, load_truetype_glyph): Update all callers.
