|
|
|
|
Allows the ability to call any one of the transform functions on
|
|
scene items within a group without updating the internal matrices of
|
|
the group until obs_sceneitem_defer_group_resize_end has been called.
|
|
|
|
This is necessary if the user is resizing items while they are within
|
|
a group, as the group's transform will automatically update its
|
|
transform every frame otherwise.
