Victor Zarubkin	c943431104	(GraphicsView) Using GraphicsScrollbar with qreal values instead of standard QScrollBar with int values. ...

Victor Zarubkin	3978535a99	Added GraphicsScrollbar (still in development phase) for big graphics scene. Standard QScrollBar's int value gets overflow very fast when doing zoom-in for graphics scene. So it is necessary to create a Scrollbar with double value.	2016-07-10 01:31:45 +03:00
