Retrospective commit from 2009-10-24.
Continue working on set_cursor_from_row. Cleanup of resolved_level and bidi_type members of struct glyph. xdisp.c (set_cursor_from_row): Fix off-by-one error when skipping over non-character glyphs at end of a reversed row. dispextern.h (struct glyph): The `resolved_level' member needs only 5 bits, not 6. The `bidi_type' member needs only 3 bits. (bidi_type_t): Rearrange so that types that can appear in the resolved type are at the beginning and have values less than 8. bidi.c: Include setjmp.h.
