5af7daabc4 Mark AVFilterPad[] compound literals as const. 
GCC 4.6.2 at least still seems to fail to put them in .rodata though,
see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303

163854bca0 vf_drawtext: drop text wrapping feature 
Or in other word, do not go to the next line when the text cannot be
rendered within the frame.

The rationale is that wrapping is hard to manage, as it depends on the
position of the text, thus making hard/impossible to compute the size
occupied by the rendered text, and makes the filter behavior
unpredictible with moving text (implemented in a pending patch).

Also the current wrapping code is very limited (for example it splits
words in the middle), and correctly handling wrapping requires much
more complexity (alignment, gravity, word parsing etc.), while
drawtext is meant to be only a thin wrapper around libfreetype, so
such advanced features don't belong here.

b87d4c2b9f vf_drawtext: do not set limitations on fontsize 
It may be needed to use values greater than 72, and in general greater
than an arbitrary big value. Let the user choose what's too big for
her.

500b3210da vf_drawtext: fix background box coloring with RGB formats != RGBA 
drawbox() expects a color specified in RGBA format, while the code was
providing a color with the components specified in the same order of
the input pixel format.

In particular, fix box coloring with AXXX RGB formats.

db56a7507e vf_drawtext: prefer int over unsigned int

79eff91325 AVOptions: deprecate av_opt_set_defaults2 
It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.
