Between 2.0.5 and 2.0.7 the bug that disabled use of embedded bitmaps
when the autohinter was not explicitly disabled was removed. When
specifying FT_LOAD_NO_BITMAP, 2.0.8 should behave like 2.0.5.

Cant say whether the embedded bitmaps in this particular font are of poor
quality or if your program doesnt check the bitmap format (with 2.0.8, if
you specify no special flag, you get gray-scaled 8bit bitmaps if no
embedded bitmap was found and b&w 1bit bitmaps if an embedded bitmap of
the specified size was found, this font seems to have embedded bitmaps
of sizes upto 22 pixels).

Ciao, Detlef
