* The VisCAM and SolidView software packages use the two "attribute byte count" bytes at the end of every triangle to store a 15-bit RGB color:
*
* bit 0 to 4 are the intensity level for blue (0 to 31),
* bits 5 to 9 are the intensity level for green (0 to 31),
* bits 10 to 14 are the intensity level for red (0 to 31),
* bit 15 is 1 if the color is valid, or 0 if the color is not valid (as with normal STL files).
