+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
+      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
+  - transform_test -> simple "walk around" test for world & view transformations
+  - light test -> test for lighting
