SVG plotter rework: use mm as units in file. Remove useless inch option.

Use 4 digits in mantissa as default and when exporting SVG.
Allow 0 as line width: this is the right value to draw filled shapes with no outline thickness.

// Note:
// During tests, we (JPC) found issues when the coordinates used 6 digits in mantissa
// especially for stroke-width using very small (but not null) values < 0.00001 mm
// So to avoid this king of issue, we are using 4 digits in mantissa
// The resolution (m_precision ) is 0.1 micron, that looks enougt for a SVG file
