Support pinch zoom gesture in the Mandelbrot example
Used QGesture for this as per the gesture example.
Moved the help and info text to separate lines.
Enabled word wrap to prevent text going off screen.
As a drive-by, the code to center the window at a size that's a fraction
of the screen is replaced with a simple sizeHint() override. The user
should have control over placement, particularly now that it should be
placed manually onto a touchscreen if the user has one.
Done-with: Shawn Rutledge
Fixes: QTBUG-96702
