- Fixed scaling option, now all parts are scaled by bipoles/length
- Surge arrester appears no more if a to path is used without []-options
- Fixed current placement now possible with paths at an angle of around 280°

* Version 0.6 (2016-06-06)
- Added Mechanical Symbols (damper,mass,spring)
- Added new connection style diamond, use (d-d)
- Added new sources voosource and ioosource (double zero-style)
- All diode can now drawn in a stroked way, just use globel option "strokediode" or stroke instead of full/empty, or D-. Use this option for compliance with DIN standard EN-60617
- Improved Shape of Diodes:tunnel diode, Zener diode, schottky diode (bit longer lines at cathode)
- Reworked igbt: New anchors G,gate and new L-shaped form Lnigbt, Lpigbt
- Improved shape of all fet-transistors and mirrored p-chan fets as default, as pnp, pmos, pfet are already. This means a backward-incompatibility, but smaller code, because p-channels mosfet are by default in the correct direction(source at top). Just remove the 'yscale=-1' from your p-chan fets at old pictures.
