Subject: Fix STR #2530 (Mac OS only). Implements a fast algorithm for
 fl_width() that memorizes the width of all characters the first time they are
 seen and computes the width of a string as the sum of the widths of its
 characters. Char widths are memorized in 256 blocks of 256 widths; only
 blocks used in some text are allocated and computed. The width of characters
 beyond U+FFFF is computed anew each time. Strings are drawn using core text,
 after having deactivated character kerning, so their width is the sum of the
 widths of their characters. This is the same algorithm as used for WIN32.
