Filament swatch with 3 lines of text

Exactly like the original, but I added the possibility of having a third line of text. The change proved to be specially useful to me because I wanted the swatch to be smaller than the default (50x30mm rather then 79.5x30mm); the font sizes had to be too small to fit so many information. Also, making the text raised by default improved significantly it readability. To have the third line, modify the variable textstring4. Last, if you are curious, I did not bother printing the text using any sort of multimaterial; I simply painted using acrylic paint.
