Add Orthographic Axis Projection Mode to Curve Drawing Tools

Hi! Blender newbie here so feel free to tell me this is a thing already.

I'm a big fan of the surface projection- super handy tool to have.

It would be very useful to have an axis projection mode to draw straight onto one of the orthographic planes, projected from the view plane.

I know I can do this by switching to an orthographic camera, which works well enough, but from a UX perspective it would be nice to add the option directly into the other projection options available to the tool. UX sugar FTW.

In regards to depth, the Z floor makes the most sense intuitively, but to support all the axis the cursor could be used as a guide for the origin of each of the planes.

Thoughts?
