[evo] Fit animation in full width

Hi !

That would be great to have an option to set golbal animation stage to fit and center homothetically on main container in full width layout.

Example:

With an initial width an height of slide set to 1280px * 720px, the slide and its animation is scaled up in width at any resolution upper to 1280px, but the max-height of the container stays at 720px. The animation is based on a stage of 720 height so elements ‘disapears’ at the bottom of the slide.

Under 1280px, objects are strangely sized, and I know why (my images are svg with width set in percents), but I assume that if the whole animation was homothetically centered on container we could see whole element and animation and only the background covers the container.

I can export the slide if you want to take a look 🙂
