Improvement #1: Replace function numbers with keywords.  This is easy enough
to code, and will simplify using the function.  For example:

         Fontmetrics("arial.ttf", min_extent, "Hello, world!")

is easier to remember and understand than

         Fontmetrics("arial.ttf", 1, "Hello, world!")
