Adaptively throttle texture uploads
We need adaptive texture uploading because we run on a wide variety
of systems and a one size fits all policy will not work.
This patch maintains a tick rate of 4ms and default upload count of
12 textures per tick, but allows for more textures per tick if we've
measured that we can be faster.
The number of partial updates allowed is also communicated from the
impl thread to the main thread at the beggining of each frame.
