Potential OIT optimization

[lexaknyazev]

Consider using OES_draw_buffers_indexed extension on supported platforms to reduce the number of render passes.

Sounds like a pretty cool extension indeed :-)

@CraigFeldspar do you think it would be simple to add ? (assuming support in the engine)

@Popov72 do you know if the same is available in WebGPU ?

[Popov72]

Yes in WebGPU you can have these settings per color target:

[Popov72]

See BabylonJS/ThePirateCove#792 which would require the support of the same extension.
