Detailed Description

Float buffer cache for image buffers.

Image buffers might not have float buffers which are required for the image engine. Image buffers are not allowed to have both a float buffer and a byte buffer as some functionality doesn't know what to do.

For this reason we store the float buffer in separate image buffers. The FloatBufferCache keep track of the cached buffers and if they are still used.
