There's two ways to do this:
GrGetFontInfo() - This fills in a structure that includes the width of
every character.
GrGCTextSize() - This calculates the width of a given string.
I suggest using GrGetFontInfo(), since that can be done once for each font
used, and
then calculate the length "locally". It doesn't matter much when the app is
linked with
Nano-X directly, but it is a LOT faster when using the network code.
