Free Hero Mesh

  Specifies the 1-based order number of the level to start at.

.margin
  The X coordinate of the left margin. To the left is the status area, and
  to the right of the margin is the playfield. This should be at least 64,
  or the picture size, whichever is greater.

.maxTrigger
  If nonzero, the maximum number of times that the trigger phase may loop
  during each turn (it starts counting from zero each turn). If it loops
  more, it displays an error message and results in loss of game. (This
  does not prevent other kinds of infinite loops, though.)

.palette
  If defined, the file name of the palette to use (if not set, then the
  internal palette is used instead). The file format is hex rrggbb format
  separated by any kind of whitespaces.

.progress
  If positive, how many steps between dots in the progress report for the
