Import with fromSVGPathData breaks circle/arc.

[NielsdeBlaauw]

What is happening

When using fromSVGPathData to generate a model from the string M77.497 2.497a75 75 0 0 1 0 150 75 75 0 0 1 0-150z, makerJS incorrectly imports the shape as a half-circle. It produces the following pathdata:

{ paths:
       { p_1:
          Arc {
            radius: 75,
            origin: [Array],
            startAngle: 270,
            endAngle: 450,
            type: 'arc' },
         p_2: Line { type: 'line', origin: [Array], end: [Array] } } }

When exported to DXF this shows:

What is expected

In the browser (tested on chrome, firefox, latest), the PathData M77.497 2.497a75 75 0 0 1 0 150 75 75 0 0 1 0-150z produces a full circle:

Also, adding an extra a in the PathData string results in the same shape in the browser, and a correct full circle model in MakerJS:

Bad:  M77.497 2.497a75 75 0 0 1 0 150 75 75 0 0 1 0-150z
Good: M77.497 2.497a75 75 0 0 1 0 150 a 75 75 0 0 1 0-150z

MakerJS converts the pathData with the extra a to a model correctly:

{ paths:
       { p_1:
          Arc {
            radius: 75,
            origin: [Array],
            startAngle: 270,
            endAngle: 450,
            type: 'arc' },
         p_2:
          Arc {
            radius: 75,
            origin: [Array],
            startAngle: 90,
            endAngle: 270,
            type: 'arc' } } }
