Error "Cannot read property 'y' of undefined" in the file ShapePath.js

See original GitHub issue

If in the file Font.js in the function createPath value glyph.o ends with text "m {number} {number} z " (e.g. "m 167 878 z ") then in the file ShapePath.js in the function isPointInsidePolygon occurs this error:

This happens, for example, when I use character “Ö” of font Calibri.

In the file ShapePath.js in the function toShapes this code:

} else {

	newShapeHoles[ mainIdx ].push( { h: tmpPath, p: tmpPoints[ 0 ] } );

should be changed to this code:

} else if ( tmpPoints.length ) {

	newShapeHoles[ mainIdx ].push( { h: tmpPath, p: tmpPoints[ 0 ] } );

Closing for now. The issue can be reopened if it’s proven that facetype.js works as intended.

The JSON file used in jsfiddle was generated using generator http://gero3.github.io/facetype.js/ and using TTF file downloaded from https://www.fontmirror.com/calibri.

I have replaced all texts "m {number} {number} z " with text "z" and now there is no error and the character “Ö” seems to be fine: https://jsfiddle.net/blizzard_mindfloat/6smn8heb/2
