How do I get the shaders to work

[PracticeBot13]

Directory structure should be as follows:

Code:

Your-colobot-directory
 - colobot.exe
 - data
   - ai
   - fonts
   - help
   ...
   - shaders
     - shaders go here

And you run Colobot using switch:

Code:

colobot.exe -graphics ###

Where ### is one of available graphics engines:

opengl -- OpenGL 1.4 engine (default)
gl21 -- OpenGL 2.1 engine
gl33 -- OpenGL 3.3 engine
auto -- automatically determines best available engine (added in dev branch)

OK. I've finally got it.
