Werner Lemberg 76fffcd898 * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value 
0x100 instead of 0x10000; the latter value is already occupied by
FT_LOAD_TARGET_LIGHT.  Bug reported by James Cloos.


Handle SFNT with neither outlines nor bitmaps.  This fixes Savannah
bug #25010.

* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
outlines nor bitmaps.

* src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there
is no table with glyphs.


* src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging
message.


Other minor cosmetics.
