export gif of rotated 3d model

[hrgdavor]

It is not too difficult, and dependency for that could be loaded on demand.

options:

• number of frames for full rotation
• delay between frames
• resolution
• background color/transparent

Additionally, maybe also support export separate images in a zip file.

nice

• simplest: around an axis, eg. z-axis
• advanced: provide vector for rotation
• difficult: provide a time->[x,y,z] function for camera position, and time->camera orientation function

another addon in addition to .gif and .zip would be export to .mp4, much more space efficient and has not the GIF 256 colors restriction. That might affect result in case of smooth render and .gif output.
