{
FPVectorial example application for writing vectorial images
generated in code to disk. This program will generate the following
vectorial images:

single_line_1    One line from (0, 20) to (30, 30)
single_line_2    One line from (20, 30) to (30, 20)
polyline_1       One line from (0, 0) to (10, 10) to (20, 30) to (30, 20)
polyline_2       One line from (10, 10) to (20, 30) to (30, 20) to (40, 40)
bezier_1         One path starting in (0, 0) lining to (10, 10) then bezier to (20, 10) and then line to (30, 0)
bezier_2         One curve from (10, 10) to (20, 20)
text_ascii       One text written at (10, 10)
text_europen     One text testing european languages at (20, 20)
text_asian       One text testing asian languages at (30, 30)
