Commit 3887b077 authored by Derk-Jan Hartman's avatar Derk-Jan Hartman

* changed default value of sub-margin to 0

* sub elements can be moved up (positive values) and down (negative)
* force_crop'ed elements cannot be moves (usually only dvd menu's)
* works for spudec and subsdec
* if the margin / offset correction forces the picture out of the main picture, the offset is cropped so that the subpicture is still 100% visible.
