| When we separate an image into it's own dedicated layer we have two copies of the data, one in system memory (owned by imglib) and one as a texture. We can teach imglib about this second copy and free the system memory one in some cases to save memory usage. This is particularly useful for mobile where image scaling is much cheaper on the GPU, but the memory cost of two copies will hurt. | | When we separate an image into it's own dedicated layer we have two copies of the data, one in system memory (owned by imglib) and one as a texture.
