 Test programs for OpenGL engine:
   - texture_test -> multitexturing test with 2 textures (included as files: ./tex1.png, ./tex2.png)
   - model_test -> simple model viewer to test model loading
-    usage: ./model_test {dxf|mod} model_file
+    usage: ./model_test {old|new_txt|new_bin} model_file
       second argument is the loaded format (DXF or Colobot .mod files)
     requires ./tex folder (or symlink) with Colobot textures
     viewer is controlled from keyboard - the bindings can be found in code
