Advanced Styling and related bugs

[FrostKiwi]

Our project's git repo is hooked up to gource to auto-generate a new video every day and display and auto-play it on a screen in front of the department. Here is how our setup looks based on my own project (https://github.com/FrostKiwi/Mirrorball), with the company's logo switched out for Github's:

Mathematical.Magic.Mirrorball.mp4

Also this Gource Explainer plays every loop, appearing subtitles also generated with Gource's message feature:

Explainer.mp4

Setting these up with Gource, I came across a couple issues:

• To see all the people's faces independent of zoom, I set --fixed-user-size. However, this setting ignores the name above the avatar and changes distance of the text to the avatar, based on zoom level, which leads to this big gap and name overlapping the photo
• Just like with the logo, being able to specify an offset in the form of 0.0x0.0, it would be great to have the same for time, because right now time can only be on top and to get it to the left this hacky workaround had to be used: --date-format " %Y年%m月%d日 %H:%M時"
• It would be great to have two more logo type overlay definitions: Header and Footer, to specify elements at the top and bottom of the screen. Right now the whole overlay is one big logo PNG, which makes it resolution dependent. I.e., a change in resolution or aspect ratio necessitates an update to logo png
• It would be great if the seed could influence the rest of the simulation, not just the colors. Sometimes the camera decides to rotate a horizontal tree vertically and have part of the graph cut-off by the screen edges. This happens randomly from time to time. It would be great to have one set seed, where the camera decided to rotate correctly and use that. Right now it seems gource is not deterministic in its simulation and camera movement
