Detailed Description

Collection of handy functions to simplify drawing shapes from within footprint wizards.

A "drawing context" is provided which can be used to set and retain settings such as line thickness and layer. The DC also contains a "transform stack", which allows easy positioning and transforming of drawn elements without lots of geometric book-keeping.
