Render Chrono Vortex using a shader effect

[pchote]

Closes #9778.

[PunkPun]

This will need an update rule, and I don't think it closes that issue just yet

[pchote]

Updated.

Will this also twist the renderable comes from ISelectionDecorations or selection bar or bound visually?

And I got this crash in current branch test, using ANGLE and Windowed.

Exception of type `System.InvalidOperationException`: OpenGL Error: See graphics.log for details.

No.

[pchote]

Updated.

[dnqbob]

Test on ANGLE and Modern in FullScreen and Windowed is OK.

My PC cannot properly run Embedded GL so I cannot give the final conclusion of the test.

Is there someone can help to test on Embedded GL?
