== Sequencer ==

This fixes Orig Dimension display (mostly).
* orx, ory both didn't get calculated, if dimension already matched
* putting them into Strip instead of StripData ment, that using images
  of different dimensions in one strip could lead to incorrect results

Still TODO: on file open, timeline display happens before preview 
display which means: orig_width and height are calculated after the 
first draw of N-keys dialog. You have to hit refresh (or scrub one 
frame) to get the right values displayed.
