Drawing Large Grids

Following PR discussion.

At Max IV we need to enable the large grid drawing.

Currently, the grid can be drawn only on the visible canvas, which is quite limiting.
Quick proposition of solution was to:

1. create two 2D points (there is a possibility of moving video left and right, zooming etc. between adding second point),
2. pick them (with CTRL pressed, moving motors still possible)
3. open the context menu with additional option visible
4. the grid is added, slightly overlapping the chosen points (bottom right) as numbers of rows and columns are integers. Order of points does not matter.

Then there are two propositions of upgrading the idea:

1. Drawing grids should start as usual for users habits (with picking Draw Grid from context menu of control buttons). And then adding options to context menu enabling choosing two points, not only by dragging which is limiting. First one could be something like Start grid from here and after picking that it could be exchanged with Finish drawing grid here.

2. Adding tab with all the shapes, where they could be easily accessed and selected, removed or whatever are the shapes actions.

Thanks @dominikatrojanowska. We discussed it here and we all agree that starting from the 2D-points is a bit confusing/misleading. We really prefer what you list as 1 above, that seems great ! Point 2 would be awesome but not strictly necessary, working with clicks on the canvas can sometimes become a tedious so a simple list would help alot.
