Fixed the example TestMultiRenderTarget

[JohnLKkk]

This case originally seemed to be written by a retired predecessor to test delayed rendering, but its content is missing. I rewritten this case to help newbies use MRT technology outside of jme.

Thanks for your contribution to JMonkeyEngine.

Please add back the "Override" annotations you removed from the java source.

It's confusing to have 2 variables named "mrtLightingMaterial". Please rename one of them.

I don't understand what the comments at the end of reshape() are for. I realize you didn't add them. Are they still relevant?

The setDepthTexture() method is deprecated. Please use the new setDepthTarget() method instead.

Okay, I have been busy adjusting the RenderPipeline recently, and I only noticed your reply today. Feel sorry...

[JohnLKkk]

The comments at the end of the reshape() method are some optimization techniques to help novices to implement MRT-based DeferredRender. To make the case as simple as possible, I have deleted these comments (these are actually the comments left by the previous predecessor)

#1654

[stephengold]

Why did you create PR #1654? I imagine it would be easier to push additional commits to this PR...

[JohnLKkk]

This PR was modified directly on the master, and the other PR was modified on my own branch'kkk'.

[stephengold]

Shall I close this one and review 1654?

[JohnLKkk]

Yes, trouble you. thanks
