[JDK-6961732] FontMetrics.getLeading() may be negative in freetype-based OpenJDK builds - Java Bug System

A small test program showed that 12 pt Deja Vu Sans was reporting
FontMetrice.getLeading() of -1, but only in OpenJDK freetype-based builds.

This is caused by freetype doing premature rounding of ascent,
descent and height, thus losing the raw data used to infer the leading.
