Pixel were missing on the last line of text when using MaxLines.
Bug 3295544
Only the last line of text includes the bottomPadding (extra line
spacing below the characters' descent. When The text is clipped using
maxLines, the desired height correctly added this value, but getLineTop
and getLineDescent are also used when the layout is drawn.
The fix is to make the layout aware of its clipping so that these
values are correctly updated.
