Zooming combined with scrolling.

[TheRedshiftRider]

In a normal zoom you start at the coordinates above the location. When using zooming and scrolling at the same time you can see more areas of the fractal you are zooming into.
What if the user could use two coordinates:

The starting point which is completely zoomed out. And the location where the user wants to zoom to.
The speed of the scrolling probably should be logarithmic to prevent that the scrolling is too fast.

-Maybe It could also be possible to combine certain directions by also setting the depth of the starting point and making two movies and put them together.

-And maybe a constant speed: that the keyframes shift a certain ammount of pixels.

A few years ago I did some experiments with smooth zooming/scrolling transitions between different zoom locations, check the video linked from here:

This doesn't map well to the keyframe technique for zoom assembly (aligning frames would be a nightmare).  I sidestepped that complication by using a tile-based renderer that caches the calculations and re-uses them where possible, at a slight cost of computing some parts that won't be in the final video (parts of tiles that overlap the edges of the viewport).

Might not be what you want, I was going for "shortest smooth path" rather than constant scrolling.
