* Example: get informations about an STL file

|
*
|
|
* Informations that can be retrieved by gmio_stl_infos_probe() are:
|
|
* - STL format of the input stream
|
|
* - Count of facets(triangles)
|
|
* - Size of the STL contents in bytes
|
|
* - STL ascii only: name of the solid
|
|
* - STL binary only: header(80-bytes)
