 *
 * Escape Codes:
 *
 * Hover the mouse over the text input box of the Show Text command to see
 * the default escape codes.  Do not use values that are already being used.
 *
 * ---Face Graphic---
 * if the Face ID Index value is 'f', use \f[1,2] in a Show Text command
 * to add the face at index 2 of Actor 1's face graphic.  Remember indexes
 * start at 0.  This escape code can be used multiple times within a
 * Show Text command to change expressions.
 *
 * ---Bust Graphic---
 * if the Bust ID Index value is 'b', use \b[filename] in a Show Text command
 * to add the bust graphic in the filename image.  This escape
 * code can be used multiple times within a Show Text command to change
 * expressions.
 *
 * ---Bust X---
 * X position where bust will be displayed
 *
 * ---Bust Y---
 * Y position where bust will be displayed
 *
 * ---Bust Width---
 * Width of an individual bust (should be 1/4 of full image width)
 *
 * ---Bust Height---
 * Height of an individual bust (should be 1/2 of full image height)
 *
 * ---Bust Text Position---
 * X position of text when a bust image is displayed. For comparison, when
 * a face image is displayed, the text position is 168.
 *
 * ---Nickname/Handle---
 * if the Nickname/Handle value is 'h', use \h[1] to show Actor 1's nickname.
