Multipass Rendering #29

Closed fand closed 7 years ago

fand commented 7 years ago

In this PR, we can do multipass rendering by adding PASSES property to settings. For example, the setting below renders 2 passes per frame.

1st pass renders to sampler2D renderBuffer. It can be used in latter passes.
2nd pass renders to the canvas, because TARGET is not specified.

{
    "PASSES": [{
        "TARGET": "renderBuffer"
    }, {}]
}

This setting format is based on ISF, but is different in some points.

WIDTH & HEIGHT is not supported. It's not so important and too difficult to implement.
PERSISTENT is not supported. Buffers are always persistent by default.
