/// (1) Before calling this function for the first time, use
/// pixaCreate() to make the %pixa that will accumulate the pix.
/// This is passed in each time pixSaveTiled() is called.
/// (2) %outwidth is the scaled width. After scaling, the image is
/// saved in the input pixa, along with a box that specifies
/// the location to place it when tiled later. Disable saving
/// the pix by setting %outwidth == 0.
/// (3) %newrow and %space specify the location of the new pix
/// with respect to the last one(s) that were entered.
/// (4) All pix are saved as 32 bpp RGB.
/// (5) If both %bmf and %textstr are defined, this generates a pix
/// with the additional text; otherwise, no text is written.
/// (6) The text is written before scaling, so it is properly
/// antialiased in the scaled pix. However, if the pix on
/// different calls have different widths, the size of the
/// text will vary.
/// (7) See pixSaveTiledOutline() for other implementation details.
