Optimization in Office

Dmitry Kazakov committed changes in [calligra/krita-bounded-pooler-kazakov] /image/tiles3:

Added a benchmark for COW to measure the pooler help

The results of the benchmark:
We measure a write access to every tile of an RGB16 image of size
4096x2048 pixels. This rewrite demands COW for every tile.
The measured time is:
o with pooler enabled: 12ms
o with pooler disabled: 94ms

the pooler is worth spending time on it ;)
