[whatwg] video background color (Was: Interpretation of video poster attribute)

[Philip Jägenstedt]

Safari already uses a transparent background by default and to me that
doesn't seem like a bad idea -- it may be best to hide small 1px
letterboxes due to rounding errors in aspect ratio calculation etc.
Setting "background-color:transparent" to override the default black is
probably less known to most authors and transparent background is also
more in line with most other HTML elements.

I would suggest eventually specifying this behavior in the rendering
section, unless someone feels that default black letterboxes is very
important.
