geo SVG parser have incorrect behavior in some transform cases.

[100pah]

Version

5.1.0

Steps to reproduce

In the new feature geoSVG, these transform is not the same as the original SVG did.

• The scale x and scale y have different sign and has rotate. (e.g., scaleX: 1, scaleY: -1, rotate: 90), .
• When the transform=method1() method2() ..." the method order not follow the order of translate scale rotate, the result might be different with the original SVG.
  • But I guess in most cases user will not manually edit the SVG transform with those method.
• When skew is used.
  • But skew not supported in this version of geoSVG.
