     * OK, the reason for this stupid fix is the following story:
     * GD1.x was capable of copying two images together and combining their palettes! GD2 is apparently not.
     * With GD2 only the palette of the dest-image is used which mostly results in totally black images when trying to
     * copy a color-ful image onto the destination.
     * The GD2-fix is to
     * 1) Create a blank TRUE-COLOR image
     * 2) Copy the destination image onto that one
     * 3) Then do the actual operation; Copying the source (top image) onto that
     * 4) ... and return the result pointer.
     * 5) Reduce colors (if we do not, the result may become strange!)
     * It works, but the resulting images is now a true-color PNG which may be very large.
     * So, why not use 'imagetruecolortopalette ($im, TRUE, 256)' - well because it does NOT WORK! So simple is that.
