Log message:
Fix handling of EBDT formats 8 and 9 (part 2).
This patch fixes the following problems in ttsbit0.c:
. Bitmaps for compound glyphs were never allocated.
. `SBitDecoder' refused to load metrics if some other metrics have
already been loaded. This condition certainly makes no sense for
recursive calls, so I've just disabled it. Another possibility
would be resetting `decoder-metrics_loaded' to false before
loading each composite component. However, we must restore the
original metrics after finishing the recursion; otherwise we can
get a misaligned glyph.
. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
causing some glyph components to be shifted too far to the right
(especially noticeable for small sizes).
Note that support for grayscale bitmaps (not necessarily compound) is
completely broken in ttsbit0.c.
* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
of `h == height'.
(tt_sbit_decoder_load_compound): Reset metrics after loading
components.
Allocate bitmap.
