Snapping improvements/revamp

[Keavon]

This covers a lot of general improvements needed for the layer and point snapping systems. Ask on Discord for parts to begin with if you're interested in working towards this. It could also be a GSoC project in its own right.

hi@Keavon,I am intrested in working this issue.

[Keavon]

@pratheekhassan21 this full issue corresponds to one of the GSoC project ideas ("Snapping system overhaul" under More ideas) in its full form, but it's big so it probably wouldn't be the ideal place to start. There are some sub-parts to it, such as this Discord discussion for fixing a bug that's part of the snapping system. I'd recommend starting with that debugging.

thank you

One snapping function that seems to be missing is the ability to snap to a grid when moving path points using the 'G' key.

Another idea is to have an option for snapping to the stroke boundary.
