Switch to 1080p output resolution by default, increase label font size

Newer processors and the recent parallel rendering merge should speed up
rendering enough to default to 1080p output. Additionally, most people
have 1080p and higher screens, so 1080p videos will look sharper when
watching.

We can leave the line width at 1.5 pixels, unless people prefer 2px or
so lines.
