This class represents a glyph of a TrueType font.

Instance variables:
bounds <Rectangle> The receiver's bounds
contours <Array of: PointArray> The compressed contours in the receiver
advanceWidth <Integer> advance width of the glyph
leftSideBearing <Integer> left side bearing
rightSideBearing <Integer> right side bearing
glyphIndex <Integer> the original index of the glyph (used for kerning)

	buildContours Build the contours in the receiver glyph. The contour is constructed by converting the points form each contour into an absolute value and then compressing the contours into PointArrays.
	initializeContours:with: Initialize the contours for creation of the glyph.

	new Answer a new instance of the receiver (which is a class) with no indexable variables. Fail if the class is indexable.
