Convert a Grease Pencil coordinate (i.e. can be 2D or 3D) to screenspace (2D).
Just like gpencil_point_to_xy(), except the resulting coordinates are floats not ints. Use this version to solve "stair-step" artifacts which may arise when roundtripping the calculations.
| r_x | The screen-space x-coordinate of the point. |
| r_y | The screen-space y-coordinate of the point. |

Project screenspace coordinates to 3D-space
For use with editing tools where it is easier to perform the operations in 2D, and then later convert the transformed points back to 3D.
