* file name : blocks_graphics_view.cpp
* ----------------- :
* creation time : 2016/06/26
* author : Victor Zarubkin
* email : v.s.zarubkin@gmail.com
* ----------------- :
* description : The file contains implementation of GraphicsScene and GraphicsView and
* : it's auxiliary classes for displyaing easy_profiler blocks tree.
* ----------------- :
* change log : * 2016/06/26 Victor Zarubkin: Moved sources from graphics_view.h
* : and renamed classes from My* to Prof*.
* :
* : * 2016/06/27 Victor Zarubkin: Added text shifting relatively to it's parent item.
* : Disabled border lines painting because of vertical lines painting bug.
* : Changed height of blocks. Variable thread-block height.
* :
* : * 2016/06/29 Victor Zarubkin: Highly optimized painting performance and memory consumption.
* :
* : * 2016/06/30 Victor Zarubkin: Replaced doubles with floats (in ProfBlockItem) for less memory consumption.
* :
* : * 2016/09/15 Victor Zarubkin: Moved sources of EasyGraphicsItem and EasyChronometerItem to separate files.
