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.
