For certain fonts with guaranteed character widths, this is possible
using a hash of all the characters widths. For example, here's the
widths of helvetica and helvetica-bold:
/*
* This is an array of character widths for a few standard fonts.
*
* Included is "h" (helvetica) and "hb" (helvetica-bold).
*
* Each element is identified by the ascii decimal value of a
* character as the key, and the width (wx) of the character as the
* value.
*
* The widths are in thousandths of a point, so you can calculate a
* characters width as follows:
*
* pt_size_of_font * wx_value / 1000
