Simple proto to draw sawtooth waveform

Waveform - Custom qml component

1. Inherited from QQuickItem
2. Used to show waveform on screen.
3. Uses QSGGeomtryNode & QSGGeomtry to plot the waveform

SawtoothGenerator - Data provider

1. getPlot ill give the point to draw one vertical line on particular pixel.
2. Struct Point is having the information about the pixel coordinates(x position, y1&y2 position).

Logic:

1. Instantiated the geometry with the QSGGeometry::defaultAttributes_Point2D() & 2000 vertices
2. In a for loop fill the 2000 vertices with data provided by getPlot call.

Note: Here one vertical line of length=5pix has been drawn on every pixels with same 5pix Increment between 1-x pixel. So the line seems to be having the jagging effect. Is there a way to make this smooth sawtooth wave without jagging effect?
