/* nftext.c
 *
 * Implements the no-flicker static text control ("td_nftext").
 *
 * This is NOT a general-purpose control (see the globals below).
 *
 * Note: most NoFlickerText controls use ANSI_VAR_FONT, but the status
 * control (ID_STATUSTXT) uses the font defined in the dialog box
 * template (e.g. Helv8).  Also, the foreground color of most NoFlickerText
 * controls is RGB_FGNFTEXT, but the foreground color of the status control
 * is whatever the current value of <grgbStatusColor> is.
 *
 * Borrowed from ToddLa (with many, many modifications).
