Anton Khirnov f712d3669e cdgraphics: do not return 0 from the decode function
0 means no data consumed, so it can trigger an infinite loop in the
caller.

Anton Khirnov 238614de67 cdgraphics: do not rely on get_buffer() initializing the frame.
Setting it to zero (instead of 128, as the default get_buffer() does)
also produces more correctly-looking output.

Xi Wang 0d3123666a cdgraphics: fix incorrect vertical offset mask in cdg_scroll()
The vertical offset mask 0x07 is suspicious.

    v_off = FFMIN(data[2] & 0x07, CDG_BORDER_HEIGHT - 1);

Note that v_off is up to 11 (CDG_BORDER_HEIGHT - 1), the correct mask
should be 0x0F.
