  * include/freetype/freetype.h (FT_Select_Size): Rename the second argument from `idx' to `strike_index'. (FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of this enum. * include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH, FT_REQUEST_HEIGHT): New macros to get the width and height of a request, in fractional pixels. * include/freetype/internal/ftobjs.h (FT_Select_Metrics, FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics, FT_Request_Metrics): New base functions to set the font metrics. They were part of FT_Select_Size/FT_Request_Size and are made independent functions so that metrics are not set again and again. * src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set only when driver's size_select/size_request is NULL. That is, drivers should set the metrics themselves. (FT_Match_Size): Round before matching. This was what we did and it does cause some problems without rounding. * src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c (tt_size_select): Set the font metrics. s/index/strike_index/. The scaled metrics are always preferred over strikes' metrics, even when some strike is selected. This is done because the strikes' metrics are not reliable, e.g., the sign of the descender is wrong for some fonts. * src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c (tt_size_request): Set the font metrics. Call cff_size_select/tt_size_select when some strike is matched. * src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c, src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c, src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c: Set the font metrics. s/index/strike_index/. * src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these files were committed. Just a catch-up. (PS_Conv_ToFixed): Remove the `goto'. (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little. * src/sfnt/ttsbit.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics), src/sfnt/ttsbit0.c (tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The advertised metrics in `available_sizes' are different from those actually used.
