//  	    ULONG32 ulFontPtSize, BOOL isBold, BOOL isItalicized,
//	    ULONG32 ulFontCharsetIndex)
//  This function takes a char (which can be a 2-byte char, thus the val
//  passed in is a UINT16) and calculates its "width" (x-extent) in pixels
//  based on its font face (e.g., "courier"), its point size, whether or not
//  it is bold and/or is italicized.  The parameter ulFontCharsetIndex tells
//  the function whether or not the character is single byte, double byte,
//  or Unicode.
