CIGAL Reference Manual, Chapter 3 (Functions): projection
usage: results = projection(ptrvarb)
PROJECTION returns an array of 12 values (RESULTS) describing the current scale, rotation, offset, and pin settings for a pointer variable (PTRVARB). The order of the 12 output values is:
Xscale, Yscale, Zscale, Xrotaion, Yrotation, Zrotation,
Xoffset, Yoffset, Zoffset, Xpin, Ypin, Zpin.
If the specified argument is not a pointer variable all returned values are 0.
