Small changes to images as planes:
*Use absolute as default size mode (dpi with BU is not that nice).
*Use default plane primitive instead of creating our own square (this way we can be sure things like verts order will always match those of default plane!), request from Christopher Barrett in tracker.

Fix #34607: MDD import should default to linear instead of bezier keyframe
