Description Sven Gothel 2015-09-28 06:52:58 CEST 
The passed inX and inY x/y offset for readPixel -> [textureData] buffer,
must be passed to readTexture.updateSubImage(..)'s destination offset.

I.e. the buffer's content starting at beginning is filled via glReadPixels
w/ offset applied.

Hence the texture update must pass the offset as the destination offset,
i.e. to be used for glTexSubImage2D's offset.

Currently zero is passed.
