The offscreen pass does not take into account the previous texture pass

[untoldengine]

For example, currently it does not take the input texture from the previous pass. You may need to modify the function arguments a bit so that the user does not need to go into the engine and make the changes.

for example, you may need to add the following:

pipeline->inputTexture=uPreviousRenderPass->getPipeline()->targetTexture;

and

[offscreenRenderEncoder setFragmentTexture:pipeline->inputTexture atIndex:fiDepthTexture];

However, keep in mind that fiDepthTexture may not be want the user wants.
