The solution is a hack. It's a workaround for another bug (#18655).
Now it's working in all modes: fullscreen, maximized screen and gameplayer.
* small change to always set the perspective mode as true during dome mode.
* Enviroment Map implemented (replacing truncated mode 2).
- Now it's possible to pre-bake animated (or static) EnvMaps to use with Cube Map textures.
* Enabling 2DFilter in Dome mode
- no GL_DEPTH_BUFFER supported though.
* Tweaking GameSettings menu (centralizing buttons)

Fixed two bugs from original patch:
- deleting a text will clear the warp field from Game framing settings
- removed spurious black dots along the edge of the cube map in the gameplayer
Known limitation:
- resizing of the screen doesn't work in the gameplayer
Known bugs:
- Texture with reflexion are not rendered correctly
- Spurious problems with light
