Consider two unit vectors (1,0) and (.6,.8) + for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. + These vectors are stored as (0x4000,0) and (0x2666,0x3333) after + rounding and F_dot_P is assigned 0x26660000. The lower bits were + already lost while rounding the unit vector components. + + Besides code simplification, this change can lead to better + performance when FT_MulDiv with the scaled-down F_dot_P is less + likely to use the costly 64-bit path. We are not changing the type + of F_dot_P to FT_F2Dot14 at this point. + + * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 + bits and modify its use accordingly. + (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify + the use of F_dot_P field. + * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary + assignment of F_dot_P to its theoretical maximum in case we decide + to scale back its type later. + +2012-12-09 Johnson Y.
