This keeps a sorted history of the texture upload rate and increases
the history size to improve consistency/accuracy and overhead.
Prior to this patch, calling ThrottledTextureUploader::estimatedTexturesPerSecond
ran a sort operation, which will be slow for larger history sizes.
Instead of keeping a FIFO history, it keeps sorted history and discards
the min and max values.
