Issue Summary

Implement independent grid / reticule division separation. This would allow the individual control of the grid / reticule horizontal (along the Y-axis) and vertical (along the X-axis) separation lines to create both uniform and non-uniform quadangular tiles that would correctly adapt to the aspect ratio of any given canvas size.

It's proposed that this setting occupies the same space on the preferences.

This will also help to implement further down the line a reactive field chart + studio templates that the animator can adapt according to their shot specifications.
