Add more grid overlay styles to the crop tool
The overlay grid of the current crop tool is based on the Rule of Thirds. There are a few more photo composition rules though, and I was wondering if you guys could implement those as an overlay as well and create a property which allows to select one of these overlay grid styles and the rotation.
Here is a list of some well-known photo composition rules with links to the theory/ calculations behind it:
Golden Section/ Phi Grid
Golden Triangle
Golden Rectangle/ Golden Spiral

Please keep in mind that you'd need to be able to rotate these new overlay grids!
