GDS2 (chip layout) viewer for the chip design engineer.
The main objective was to focus on the basic functionality but adding some
useful features that many, even commercial viewers don't have:
* shows the design as it is
* can animate layers to make them blink or scroll the fill pattern.
* display a layer "marked" by drawing a small cross on all shapes<
All comes wrapped in a nice, Qt based state of the art GUI. Usage of the viewer
is simple and is similar to that of other tools.
