ui: Hide slice implementation details from subclasses For performance we want to stash some data for each slice that is only relevant to the base class (specifically 'x' the pixel offset and 'w' the pixel width of the slice). This change uses some type magic to hide these properties from subclasses to avoid that people start depending on them. Bug: 207474444 Change-Id: I4022d5031067f5122500c6d3de0fdbb001b7ad60
