Fix vanishing labels for first and last ticks....
Fix vanishing labels for first and last ticks. Extra space must be reserved by layout for the axes that have wide labels for first or last tick. Changed the logic how axis sizeHint is interpreted to make the previously irrelevant height or width (depending on orientation) of the sizeHint to indicate how far the widest label extends past the first/last tick, and adjust the grid size accordingly in layout.

The example shows how to create your own custom zooming effect with QRubberBand by using a mouse
and how to use touch gestures for paning and zooming.

Let's first create a line series with some example data.
\snippet ../examples/zoomlinechart/main.cpp 1
Then we create a custom chart view by deriving from QChartView:
\snippet ../examples/zoomlinechart/chartview.h 1
We override mouse and key event handling
\snippet ../examples/zoomlinechart/chartview.h 2
Then we implement a custom logic for mouse and key events. For example pressing '+' key will zoom in and pressing
the '-' key will zoom out.
\snippet ../examples/zoomlinechart/chartview.cpp 1
We also create our own QChart:
\snippet ../examples/zoomlinechart/chart.h 1
Where we can handle the gestures:
\snippet ../examples/zoomlinechart/chart.cpp 1
Note that you will need to call grabGesture() to both QMainWindow and QChart.
