Some need fix?

line margin if is set(excepet zero),is force to cover the margin set in style.

Could you go in more details?

(When calculating positions, the bigger margin of style & line is choosen.)

[SuJiKiNen]

line_margin > 0 ? line_margin : style_margin

See function call math.max in lines like here.

My parser reads data as they are, so a line/dialog has a margin (like in ASS text) and the related style (styleref) another.
For position calculation, the bigger one is selected, because there it matters.

the subtitle filter don't act this way,and I think line force way is much better,similar to inline fx.

Ah, an implementation matter. Fixed it in last commit, thanks.
