Get point at a specified distance along the stroke.

This will return the x,y position of a point at a given distance along the stroke. The distance will be obtained by first digitizing the curve internally and then walking along the curve. For a closed stroke the start of the path is the first point on the path that was created. This might not be obvious. If the stroke is not long enough, a \"valid\" flag will be FALSE.

`dist` : | The given distance.
`precision` : | The precision used for the approximation.
`x_point` : | The x position of the point.
`y_point` : | The y position of the point.
`slope` : | The slope (dy / dx) at the specified point.
