masque 2D CAD library
masque is an attempt to make a relatively small library for designing lithography
masks. The general idea is to implement something resembling the GDSII file-format, but
with some vectorized element types (eg. circles, not just polygons), better support for
E-beam doses, and the ability to output to multiple formats.
Pattern is a basic object containing a 2D lithography mask, composed of a list of Shape
objects and a list of SubPattern objects.
SubPattern provides basic support for nesting Pattern objects within each other, by adding
offset, rotation, scaling, and other such properties to a Pattern reference.
Note that the methods for these classes try to avoid copying wherever possible, so unless
otherwise noted, assume that arguments are stored by-reference.

- matplotlib [Pattern.visualize(...)]
- python-gdsii [masque.file.gdsii]
- svgwrite [masque.file.svg]
