NAME
	FontExtent -- get the font attributes of the current font (V36)

   SYNOPSIS
	FontExtent(font, fontExtent)
	           A0    A1

	void FontExtent(struct TextFont *, struct TextExtent *);

   FUNCTION
	This function fills the text extent structure with a bounding
	(i.e. maximum) extent for the characters in the specified font.

   INPUTS
	font       - the TextFont from which the font metrics are extracted.
	fontExtent - the TextExtent structure to be filled.

   RESULT
	fontExtent is filled.

   NOTES
	The TextFont, not the RastPort, is specified -- unlike
	TextExtent(), effect of algorithmic enhancements is not
	included, nor does te_Width include any effect of
	rp_TxSpacing.  The returned te_Width will be negative only
	when FPF_REVPATH is set in the tf_Flags of the font -- the
	effect of left-moving characters is ignored for the width of
	a normal font, and the effect of right-moving characters is
	ignored if a REVPATH font.  These characters will, however,
	be reflected in the bounding extent.
