Fix bug of propertional shifting of sh_stext_t. Original - sh_stext_t does not apply shifting of text himself to scaled font face, but - apply aggreagated matrix to font face. - shifting in parent parent coord_t would applied to scaled font. - amount of shifting is also multiplied by aggreagated matrix. - It means shiftings of parent coord_ts are applied two times. Now, - remove x, y shifting from aggreagated matrices before applying to scaled fonts.
