 Sample code: Convert old-style shapes (sticks are Joints) to new style (sticks are Parts)
 Usage: shapeconvert [-sSHAPE] [-tTHICKNESS] [genotype_or_stdin]

 Calling examples:

 # convert any genotype to f0 using new-style shapes:
 shapeconvert "X"

 //0
 m:
 p:0.5, sh=3, sx=0.5, sy=0.200000002980232, sz=0.200000002980232, rx=-1.5707963267949, rz=3.14159265358979

 # load a genotype from file, convert to new shapes, display:
 loader_test data/other.gen "Bird" | shapeconvert -s1 - | theater.exe -g -
