More curve options in sculpt and paint modes

Hi,

I love the curve stroke in Sculpt Mode, Vertex Paint and Texture Paint modes, but it's very limited at the moment. You always have to create an arbitrary curve first, that's independent of Blender's regular curves.

My suggestions:

• More curve stroke shapes to choose from, like a circle, square and ngon.

• An option to project and lock a curve stroke onto a mesh surface, so the stroke will remain sticky and not lose its screen space alignment to a mesh surface.

• An option to convert regular Blender curves to strokes and vice versa. That way you could use complex curves as strokes, like an imported SVG logo.

Thanks.
