Subclass of AbstractFont

Class comment:

I represent a font that uses TrueType derived glyph. Upon a request for glyph for a character through a call to #formOf: (or #widthOf:), I first search corresponding glyph in the cache. If there is not, it creates a 32bit depth form with the glyph.

The cache is weakly held. The entries are zapped at full GC.


Important method:
 displayString: aString on: aBitBlt from: startIndex to: stopIndex at: aPoint kern: kernDelta baselineY: baselineY


This method is called from
   DisplayText composeForm
 Project composeDisplayTextIntoForm: displayText
It uses TTGlyph to create an instance of Form.

March 2022: new import method, see comment.
