Automatically add transform strips to imported pictures about blender-power-sequencer

[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

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.
