[FFmpeg-devel] [PATCH] vf_drawtext: drop text wrapping feature

[Stefano Sabatini]

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).
