Configure precision (for floating-point rounding)

[valeriyo]

Currently, the output floats use 3-decimal digit precision, which is many cases (like 24x24 icons) is an overkill.

It would be neat, to be able to configure the floating point rounding to say, 2 digits.

Example:

        curveTo(9.224f, 14.336f, 9.324f, 14.744f, 9.46f, 15.112f)
        curveTo(9.604f, 15.48f, 9.8f, 15.772f, 10.048f, 15.988f)
        curveTo(10.296f, 16.204f, 10.616f, 16.312f, 11.008f, 16.312f)
        curveTo(11.352f, 16.312f, 11.648f, 16.268f, 11.896f, 16.18f)
        curveTo(12.152f, 16.092f, 12.416f, 15.964f, 12.688f, 15.796f)
        curveTo(12.36f, 15.604f, 12.112f, 15.308f, 11.944f, 14.908f)
        curveTo(11.776f, 14.508f, 11.664f, 14.048f, 11.608f, 13.528f)
        curveTo(11.552f, 13.008f, 11.524f, 12.472f, 11.524f, 11.92f)
        curveTo(11.524f, 11.4f, 11.54f, 10.908f, 11.572f, 10.444f)
        curveTo(11.604f, 9.98f, 11.62f, 9.52f, 11.62f, 9.064f)
        curveTo(11.62f, 8.768f, 11.596f, 8.488f, 11.548f, 8.224f)
        curveTo(11.508f, 7.952f, 11.416f, 7.732f, 11.272f, 7.564f)
        curveTo(11.128f, 7.388f, 10.904f, 7.3f, 10.6f, 7.3f)
        curveTo(10.376f, 7.3f, 10.164f, 7.328f, 9.964f, 7.384f)
        curveTo(9.764f, 7.44f, 9.56f, 7.512f, 9.352f, 7.6f)
        curveTo(9.272f, 7.512f, 9.16f, 7.44f, 9.016f, 7.384f)
        curveTo(8.872f, 7.328f, 8.696f, 7.3f, 8.488f, 7.3f)
        curveTo(7.936f, 7.3f, 7.464f, 7.384f, 7.072f, 7.552f)
        curveTo(6.68f, 7.72f, 6.304f, 7.928f, 5.944f, 8.176f)
        curveTo(5.992f, 8.376f, 6.044f, 8.588f, 6.1f, 8.812f)
        curveTo(6.156f, 9.036f, 6.204f, 9.248f, 6.244f, 9.448f)
        curveTo(6.108f, 9.752f, 5.94f, 10.092f, 5.74f, 10.468f)
        curveTo(5.548f, 10.844f, 5.348f, 11.236f, 5.14f, 11.644f)
        curveTo(4.932f, 12.052f, 4.736f, 12.46f, 4.552f, 12.868f)
        curveTo(4.368f, 13.268f, 4.216f, 13.652f, 4.096f, 14.02f)

@valeriyo please take a look previous discussion about float precision #71

This function for icon size 24x24 returns following precision "#.###" (playground)
