MadButterfly: src/shape_stext.c annotate

annotate src/shape_stext.c @ 760:5781b2485e38

Fix position issue of stext. Sometime, stext does not show at correct position. After some study, it is caused by a typo in the code of create scaled font (make_scaled_font_face()). The typo causes a fault in compute transform matrix for scale fonts.
