// MAKETEXT - Constructs a single-frame text sprite: returns a handle to a
// FLOATING memory block containing the sprite, given a
// null-terminated string, max width allowed, pen color and
// pointer to required character set.
//
// NB 1) The routine does not create a standard file header or
// an anim header for the text sprite - the data simply begins
// with the frame header.
//
// NB 2) If pen color is zero, it copies the characters into
// the sprite without remapping the colors.
// ie. It can handle both the standard 2-color font for speech
// and any multicolored fonts for control panels, etc.
//
// Based on textsprt.c as used for Broken Sword 1, but updated
// for new system by JEL on 9oct96 and updated again (for font
// as a resource) on 5dec96.
