Automatically add transform strips to imported pictures

[NathanLovato]

The add-on offers a tool to quickly center the image strips' pivot, resize them to fit their original size, and add a transform strip to quickly move and animate it with VSE Transform.
If you loop over newly imported pictures and try to use this operator, you get a ZeroDivisionError. It seems Blender doesn't store an image's width and height (keeps it at 0) unless it's buffered/rendered on screen.

Workaround idea: move the time cursor to the start of each img strip and run the setup function on each of them individually?

[NathanLovato]

Placing the time cursor over the strips from the code doesn't work, and refreshing the sequencer doesn't either. Needs more testing.

[NathanLovato]

Only pictures that rendered at least once have their image_width and image_height components initialized. Upon import, the first image strip gets rendered/initialized, but for the others, both values stay at 0:

s.elements[0].orig_width
s.elements[0].orig_height

[NathanLovato]

Possible hacky solution: import them all stacked, add transform strips, then space them out?

[NathanLovato]

Stacking the img strips doesn't work either. You must generate some kind of preview of the pictures. This probably needs a fix on Blender's side.
