[Paraview] Grid seeds for streamlines?

[John Biddiscombe]

I've been working on a new class called vtkRegularGridSource and a 
widget to control it derived from BoxWidgetRepresentation plus 
pqRegularGridSourceWidget, it allows a 2D/3D grid to be defined via the 
gui (same as one would for line source for example) - it doesn't have to 
be axis aligned and can be rotated, scaled etc using the box widget. 
Once it's ready, it should be relatively easy to inject it into the gui 
along with other widgets so that the streamline filter (for example) can 
have it in the widget selection box for inputs.

It is mostly working in my own paraview tree, but will be commited to 
cvs after 3.6 is out of the door I expect.

> Instead of using random points or a line for seeds when doing streamlines, is it possible to do this from a grid? I know I can do it many times with lines, and save these as custom filters, but each time I save then load custom filters I have to re-enter all  the data about line widths, colors, etc.
