Are we having fun yet??? 
The transform statement is generated by the graphics editor when an element has been altered from its original orientation. In a through hole connector, with original orientation, the connectors in FZ PCB View will have the multicolored red halo. If I rotate it, a transform statement will be generated and the connector will only have a red dot in the center.
As for the SVG format, what ever unit the .svg file is in (in, mm, px...) that will be the unit throughout the rest of the document unless the unit is specified. If I import a .svg file into Inkscape that is in inches, then the dimensions in the XML editor are in inches... If I start a new document in Inkscape, it defaults to pixels (px), and the dimensions in the XML editor are in pixels. I don't know if there is a way to set the default units or change the units in the Inkscape XML editor or not.
