+    glyphs. The font height is defined as
+    ascent+descent+internalLeading, and therefore not explicitly
+    included here.<p>
+
+    Please note that when querying FontMetrics from an XCanvasFont
+    interface, all values here are given relative to the font cell
+    size. That means, the referenceCharWidth and/or
+    ascent+descent+internalLeading will approximately (rounded to
+    integer device resolution, or exactly, if fractional font
+    rendering is enabled) match the referenceAdvancement/cellSize
+    members of the FontRequest for which the XCanvasFont was
+    queried. Please be aware that the values returned in this
+    structure only map one-to-one to device pixel, if the combined
+    rendering transformation for text output equals the identity
+    transformation. Otherwise, the text output (and thus the resulting
+    metrics) will be subject to that transformation. Depending on the
+    underlying font technology, actual device output might be off by
+    up to one device pixel from the transformed metrics.
