- Isolate it into it's own namespace
- Shorten function names, the namespace self-documents.
- Just use the std I/O, we can just write directly to the stream for
logging.
Trying to use GetDepthMatrixProgram outside of
TCacheEntry::FromRenderTarget is a bad idea, so don't. Instead, use a
shader which only copies the input.

This option was known to break every second game and only boost a bit.
It also seems to be broken because of streaming into pinned memory and buffer storage buffers.

The usual way to handle this kind of request is to rise a flag which the gpu thread polls.
The gpu thread itself either generates the result or just write zeros if disabled.
After this, it rise another flag which says that this work is done.
So if disabled, we still have the cpu-gpu round trip time. This commit just returns 0 on the cpu thread
instead of playing ping pong...
