Chris Bass	2863a55a89	ttml: Add support for IMSC 1.0.1 fillLineGap attribute ... Strictly speaking, the TTML spec requires that text backgrounds extend only to the font height of the related text, rather than to the vertical distance between lines. The result of this is that there will typically be vertical gaps between line backgrounds through which moving video can be seen. Since this was unnacceptable to some content providers, v1.0.1 of the IMSC spec (which profiles TTML) adds a new attribute, itts:fillLineGap[1], that allows content authors to specify that clients should extend text backgrounds such that there are no gaps between lines. This attribute is also going to be included in the next release of EBU-TT-D. This patch adds support for fillLineGap to ttmlparse and ttmlrender.
