Patch: pango font metrics

[Thomas Fitzsimmons]

Hello,

This patch updates GdkFontMetrics to use the Pango API where before it
used XLFDs.  It is a temporary fix and doesn't produce precise metrics;
Graydon's GdkClasspathFontPeerMetrics patches will supersede this work
when the supporting Java2D code is activated.

OK to commit?

	Pass font name, not XLFD, to initState.
	(stringWidth(String, int, String)): New method.
	(stringWidth(String)): Call new stringWidth.
