offapi: document queryLogicalAdvancements() for XTextLayout.
Based on implementation, explain the definition of logical
advancements for RTL and LTR case and remove incorrect part.
Logical advancements are distances to the edge instead of
widths of characters, so summing all do not yield the
total.
