Fix T70905: Image Editor header hides mask, cache and keyframe info if
flipped to bottom

While flipping the header to bottom works in the MCE (because MCE doesnt
allow overlapping UI) we need to take the regions visible rect into
account for the Image Editor.

Also correct clickable scubbing area (poll for frame_change) in the
Image Editor and the MovieClip Editor not taking UI_DPI_FAC into
account.
