If there is a 'SMV0' tag, but no 'fmt' tag, it is possible that
'st' got used as NULL.

It adds the following header to the HTML files:

which helps some browsers to display correctly the few non-ASCII
characters in the doc.

These filters are designed for storing and transmitting video sequences
with alpha using higher-efficiency codecs such as x264 which don't
natively support an alpha channel. 'alphaextract' takes an input stream
with an alpha channel and returns a video containing just the alpha
component as a grayscale value; 'alphamerge' takes an RGB or YUV stream
and adds an alpha channel recovered from a second grayscale stream.

Avoid fastidious creation and immediate destroy of the display in case
one of the dither options fails to be set.

Also add NULL checks in write_trailer(), which are now necessary since
the function can be called when not all the components have been
initialized.

More consistent with libcaca function names. Should not harm since the
device was added less than one day ago.

'mono' came before 'mono16' in the list of colorspace alternatives,
causing files of the latter type to be parsed as the former.

Set picture type before calling get_buffer.
This allows the DR application to make better decisions.
It also fixes a resource leak in case of missing reference frames
since it would call get_buffer but never release_buffer.
Also use FFSWAP to ensure that the AVFrame is properly initialized
in the next get_buffer (in particular that data[0] is NULL).
